Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538116, here are decompositions:
- 3 + 31538113 = 31538116
- 53 + 31538063 = 31538116
- 83 + 31538033 = 31538116
- 227 + 31537889 = 31538116
- 257 + 31537859 = 31538116
- 293 + 31537823 = 31538116
- 557 + 31537559 = 31538116
- 569 + 31537547 = 31538116
Showing the first eight; more decompositions exist.
