Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545970, here are decompositions:
- 11 + 31545959 = 31545970
- 17 + 31545953 = 31545970
- 47 + 31545923 = 31545970
- 83 + 31545887 = 31545970
- 227 + 31545743 = 31545970
- 233 + 31545737 = 31545970
- 257 + 31545713 = 31545970
- 347 + 31545623 = 31545970
Showing the first eight; more decompositions exist.
