Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545968, here are decompositions:
- 67 + 31545901 = 31545968
- 109 + 31545859 = 31545968
- 127 + 31545841 = 31545968
- 229 + 31545739 = 31545968
- 499 + 31545469 = 31545968
- 577 + 31545391 = 31545968
- 757 + 31545211 = 31545968
- 787 + 31545181 = 31545968
Showing the first eight; more decompositions exist.
