Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517168, here are decompositions:
- 19 + 31517149 = 31517168
- 157 + 31517011 = 31517168
- 349 + 31516819 = 31517168
- 379 + 31516789 = 31517168
- 439 + 31516729 = 31517168
- 499 + 31516669 = 31517168
- 541 + 31516627 = 31517168
- 601 + 31516567 = 31517168
Showing the first eight; more decompositions exist.
