Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517234, here are decompositions:
- 3 + 31517231 = 31517234
- 37 + 31517197 = 31517234
- 223 + 31517011 = 31517234
- 241 + 31516993 = 31517234
- 283 + 31516951 = 31517234
- 457 + 31516777 = 31517234
- 601 + 31516633 = 31517234
- 607 + 31516627 = 31517234
Showing the first eight; more decompositions exist.
