Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617968, here are decompositions:
- 7 + 31617961 = 31617968
- 79 + 31617889 = 31617968
- 97 + 31617871 = 31617968
- 157 + 31617811 = 31617968
- 211 + 31617757 = 31617968
- 271 + 31617697 = 31617968
- 337 + 31617631 = 31617968
- 409 + 31617559 = 31617968
Showing the first eight; more decompositions exist.
