Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545422, here are decompositions:
- 31 + 31545391 = 31545422
- 43 + 31545379 = 31545422
- 79 + 31545343 = 31545422
- 211 + 31545211 = 31545422
- 241 + 31545181 = 31545422
- 331 + 31545091 = 31545422
- 373 + 31545049 = 31545422
- 421 + 31545001 = 31545422
Showing the first eight; more decompositions exist.
