Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542976, here are decompositions:
- 5 + 31542971 = 31542976
- 149 + 31542827 = 31542976
- 167 + 31542809 = 31542976
- 317 + 31542659 = 31542976
- 389 + 31542587 = 31542976
- 467 + 31542509 = 31542976
- 557 + 31542419 = 31542976
- 599 + 31542377 = 31542976
Showing the first eight; more decompositions exist.
