Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545908, here are decompositions:
- 7 + 31545901 = 31545908
- 67 + 31545841 = 31545908
- 241 + 31545667 = 31545908
- 409 + 31545499 = 31545908
- 421 + 31545487 = 31545908
- 439 + 31545469 = 31545908
- 577 + 31545331 = 31545908
- 727 + 31545181 = 31545908
Showing the first eight; more decompositions exist.
