Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545942, here are decompositions:
- 19 + 31545923 = 31545942
- 23 + 31545919 = 31545942
- 41 + 31545901 = 31545942
- 83 + 31545859 = 31545942
- 101 + 31545841 = 31545942
- 179 + 31545763 = 31545942
- 193 + 31545749 = 31545942
- 199 + 31545743 = 31545942
Showing the first eight; more decompositions exist.
