Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508804, here are decompositions:
- 13 + 31508791 = 31508804
- 73 + 31508731 = 31508804
- 127 + 31508677 = 31508804
- 157 + 31508647 = 31508804
- 277 + 31508527 = 31508804
- 571 + 31508233 = 31508804
- 577 + 31508227 = 31508804
- 601 + 31508203 = 31508804
Showing the first eight; more decompositions exist.
