Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545960, here are decompositions:
- 7 + 31545953 = 31545960
- 37 + 31545923 = 31545960
- 41 + 31545919 = 31545960
- 59 + 31545901 = 31545960
- 73 + 31545887 = 31545960
- 101 + 31545859 = 31545960
- 197 + 31545763 = 31545960
- 211 + 31545749 = 31545960
Showing the first eight; more decompositions exist.
