Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617470, here are decompositions:
- 13 + 31617457 = 31617470
- 61 + 31617409 = 31617470
- 67 + 31617403 = 31617470
- 97 + 31617373 = 31617470
- 109 + 31617361 = 31617470
- 271 + 31617199 = 31617470
- 337 + 31617133 = 31617470
- 397 + 31617073 = 31617470
Showing the first eight; more decompositions exist.
