Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545498, here are decompositions:
- 11 + 31545487 = 31545498
- 29 + 31545469 = 31545498
- 59 + 31545439 = 31545498
- 97 + 31545401 = 31545498
- 107 + 31545391 = 31545498
- 167 + 31545331 = 31545498
- 181 + 31545317 = 31545498
- 199 + 31545299 = 31545498
Showing the first eight; more decompositions exist.
