Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539982, here are decompositions:
- 11 + 31539971 = 31539982
- 269 + 31539713 = 31539982
- 311 + 31539671 = 31539982
- 389 + 31539593 = 31539982
- 569 + 31539413 = 31539982
- 653 + 31539329 = 31539982
- 839 + 31539143 = 31539982
- 1031 + 31538951 = 31539982
Showing the first eight; more decompositions exist.
