Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181708, here are decompositions:
- 41 + 181667 = 181708
- 89 + 181619 = 181708
- 101 + 181607 = 181708
- 251 + 181457 = 181708
- 269 + 181439 = 181708
- 311 + 181397 = 181708
- 347 + 181361 = 181708
- 431 + 181277 = 181708
Showing the first eight; more decompositions exist.
