Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516748, here are decompositions:
- 19 + 31516729 = 31516748
- 79 + 31516669 = 31516748
- 181 + 31516567 = 31516748
- 229 + 31516519 = 31516748
- 337 + 31516411 = 31516748
- 421 + 31516327 = 31516748
- 547 + 31516201 = 31516748
- 619 + 31516129 = 31516748
Showing the first eight; more decompositions exist.
