Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545768, here are decompositions:
- 5 + 31545763 = 31545768
- 19 + 31545749 = 31545768
- 29 + 31545739 = 31545768
- 31 + 31545737 = 31545768
- 101 + 31545667 = 31545768
- 127 + 31545641 = 31545768
- 139 + 31545629 = 31545768
- 157 + 31545611 = 31545768
Showing the first eight; more decompositions exist.
