Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545722, here are decompositions:
- 223 + 31545499 = 31545722
- 283 + 31545439 = 31545722
- 331 + 31545391 = 31545722
- 349 + 31545373 = 31545722
- 379 + 31545343 = 31545722
- 541 + 31545181 = 31545722
- 631 + 31545091 = 31545722
- 661 + 31545061 = 31545722
Showing the first eight; more decompositions exist.
