Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511708, here are decompositions:
- 31 + 31511677 = 31511708
- 97 + 31511611 = 31511708
- 139 + 31511569 = 31511708
- 157 + 31511551 = 31511708
- 181 + 31511527 = 31511708
- 271 + 31511437 = 31511708
- 331 + 31511377 = 31511708
- 367 + 31511341 = 31511708
Showing the first eight; more decompositions exist.
