Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545912, here are decompositions:
- 11 + 31545901 = 31545912
- 53 + 31545859 = 31545912
- 71 + 31545841 = 31545912
- 149 + 31545763 = 31545912
- 163 + 31545749 = 31545912
- 173 + 31545739 = 31545912
- 199 + 31545713 = 31545912
- 271 + 31545641 = 31545912
Showing the first eight; more decompositions exist.
