Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531716, here are decompositions:
- 37 + 31531679 = 31531716
- 67 + 31531649 = 31531716
- 89 + 31531627 = 31531716
- 137 + 31531579 = 31531716
- 193 + 31531523 = 31531716
- 233 + 31531483 = 31531716
- 263 + 31531453 = 31531716
- 313 + 31531403 = 31531716
Showing the first eight; more decompositions exist.
