Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511624, here are decompositions:
- 13 + 31511611 = 31511624
- 73 + 31511551 = 31511624
- 97 + 31511527 = 31511624
- 283 + 31511341 = 31511624
- 337 + 31511287 = 31511624
- 457 + 31511167 = 31511624
- 631 + 31510993 = 31511624
- 691 + 31510933 = 31511624
Showing the first eight; more decompositions exist.
