Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545766, here are decompositions:
- 3 + 31545763 = 31545766
- 17 + 31545749 = 31545766
- 23 + 31545743 = 31545766
- 29 + 31545737 = 31545766
- 53 + 31545713 = 31545766
- 137 + 31545629 = 31545766
- 167 + 31545599 = 31545766
- 359 + 31545407 = 31545766
Showing the first eight; more decompositions exist.
