Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517966, here are decompositions:
- 3 + 31517963 = 31517966
- 13 + 31517953 = 31517966
- 79 + 31517887 = 31517966
- 313 + 31517653 = 31517966
- 349 + 31517617 = 31517966
- 379 + 31517587 = 31517966
- 409 + 31517557 = 31517966
- 433 + 31517533 = 31517966
Showing the first eight; more decompositions exist.
