Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617590, here are decompositions:
- 3 + 31617587 = 31617590
- 7 + 31617583 = 31617590
- 31 + 31617559 = 31617590
- 61 + 31617529 = 31617590
- 97 + 31617493 = 31617590
- 181 + 31617409 = 31617590
- 211 + 31617379 = 31617590
- 229 + 31617361 = 31617590
Showing the first eight; more decompositions exist.
