Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545086, here are decompositions:
- 3 + 31545083 = 31545086
- 19 + 31545067 = 31545086
- 37 + 31545049 = 31545086
- 163 + 31544923 = 31545086
- 229 + 31544857 = 31545086
- 337 + 31544749 = 31545086
- 367 + 31544719 = 31545086
- 373 + 31544713 = 31545086
Showing the first eight; more decompositions exist.
