Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623762, here are decompositions:
- 31 + 31623731 = 31623762
- 41 + 31623721 = 31623762
- 59 + 31623703 = 31623762
- 61 + 31623701 = 31623762
- 139 + 31623623 = 31623762
- 173 + 31623589 = 31623762
- 239 + 31623523 = 31623762
- 241 + 31623521 = 31623762
Showing the first eight; more decompositions exist.
