Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531488, here are decompositions:
- 5 + 31531483 = 31531488
- 17 + 31531471 = 31531488
- 31 + 31531457 = 31531488
- 67 + 31531421 = 31531488
- 71 + 31531417 = 31531488
- 89 + 31531399 = 31531488
- 227 + 31531261 = 31531488
- 239 + 31531249 = 31531488
Showing the first eight; more decompositions exist.
