Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545668, here are decompositions:
- 61 + 31545607 = 31545668
- 181 + 31545487 = 31545668
- 199 + 31545469 = 31545668
- 229 + 31545439 = 31545668
- 277 + 31545391 = 31545668
- 337 + 31545331 = 31545668
- 457 + 31545211 = 31545668
- 487 + 31545181 = 31545668
Showing the first eight; more decompositions exist.
