Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457488, here are decompositions:
- 17 + 31457471 = 31457488
- 191 + 31457297 = 31457488
- 317 + 31457171 = 31457488
- 389 + 31457099 = 31457488
- 449 + 31457039 = 31457488
- 479 + 31457009 = 31457488
- 659 + 31456829 = 31457488
- 701 + 31456787 = 31457488
Showing the first eight; more decompositions exist.
