Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545380, here are decompositions:
- 7 + 31545373 = 31545380
- 37 + 31545343 = 31545380
- 199 + 31545181 = 31545380
- 283 + 31545097 = 31545380
- 313 + 31545067 = 31545380
- 331 + 31545049 = 31545380
- 379 + 31545001 = 31545380
- 439 + 31544941 = 31545380
Showing the first eight; more decompositions exist.
