Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531752, here are decompositions:
- 73 + 31531679 = 31531752
- 103 + 31531649 = 31531752
- 113 + 31531639 = 31531752
- 173 + 31531579 = 31531752
- 229 + 31531523 = 31531752
- 269 + 31531483 = 31531752
- 281 + 31531471 = 31531752
- 331 + 31531421 = 31531752
Showing the first eight; more decompositions exist.
