Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517776, here are decompositions:
- 47 + 31517729 = 31517776
- 53 + 31517723 = 31517776
- 137 + 31517639 = 31517776
- 179 + 31517597 = 31517776
- 197 + 31517579 = 31517776
- 233 + 31517543 = 31517776
- 359 + 31517417 = 31517776
- 383 + 31517393 = 31517776
Showing the first eight; more decompositions exist.
