Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517984, here are decompositions:
- 31 + 31517953 = 31517984
- 73 + 31517911 = 31517984
- 97 + 31517887 = 31517984
- 283 + 31517701 = 31517984
- 331 + 31517653 = 31517984
- 367 + 31517617 = 31517984
- 397 + 31517587 = 31517984
- 457 + 31517527 = 31517984
Showing the first eight; more decompositions exist.
