Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545452, here are decompositions:
- 13 + 31545439 = 31545452
- 61 + 31545391 = 31545452
- 73 + 31545379 = 31545452
- 79 + 31545373 = 31545452
- 109 + 31545343 = 31545452
- 241 + 31545211 = 31545452
- 271 + 31545181 = 31545452
- 733 + 31544719 = 31545452
Showing the first eight; more decompositions exist.
