You can do it step by step:

c3b7c35f28c8a6089657b848366fb2e0a48d35e36b2184ef0dff520e217cad3c
cb7baee72882261268c582ebfcfee7e1cfbd166f8de3ff2182a11228d9d98217

Since both start with c, you can delete hex number:

3b7c35f28c8a6089657b848366fb2e0a48d35e36b2184ef0dff520e217cad3c
b7baee72882261268c582ebfcfee7e1cfbd166f8de3ff2182a11228d9d98217

Then change from Hex to Dec:

1681619964631834736909946030163359158422230413764693755437230999161102183740

then rest them and that's all your possible combinations in that range:
