Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545946, here are decompositions:
- 23 + 31545923 = 31545946
- 59 + 31545887 = 31545946
- 197 + 31545749 = 31545946
- 233 + 31545713 = 31545946
- 317 + 31545629 = 31545946
- 347 + 31545599 = 31545946
- 617 + 31545329 = 31545946
- 647 + 31545299 = 31545946
Showing the first eight; more decompositions exist.
