Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499776, here are decompositions:
- 239 + 31499537 = 31499776
- 317 + 31499459 = 31499776
- 389 + 31499387 = 31499776
- 449 + 31499327 = 31499776
- 467 + 31499309 = 31499776
- 479 + 31499297 = 31499776
- 509 + 31499267 = 31499776
- 587 + 31499189 = 31499776
Showing the first eight; more decompositions exist.
