Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517224, here are decompositions:
- 17 + 31517207 = 31517224
- 197 + 31517027 = 31517224
- 251 + 31516973 = 31517224
- 383 + 31516841 = 31517224
- 443 + 31516781 = 31517224
- 467 + 31516757 = 31517224
- 521 + 31516703 = 31517224
- 593 + 31516631 = 31517224
Showing the first eight; more decompositions exist.
