Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545964, here are decompositions:
- 5 + 31545959 = 31545964
- 11 + 31545953 = 31545964
- 41 + 31545923 = 31545964
- 227 + 31545737 = 31545964
- 251 + 31545713 = 31545964
- 353 + 31545611 = 31545964
- 557 + 31545407 = 31545964
- 563 + 31545401 = 31545964
Showing the first eight; more decompositions exist.
