Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531596, here are decompositions:
- 17 + 31531579 = 31531596
- 73 + 31531523 = 31531596
- 113 + 31531483 = 31531596
- 139 + 31531457 = 31531596
- 179 + 31531417 = 31531596
- 193 + 31531403 = 31531596
- 197 + 31531399 = 31531596
- 227 + 31531369 = 31531596
Showing the first eight; more decompositions exist.
