Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544212, here are decompositions:
- 5 + 31544207 = 31544212
- 23 + 31544189 = 31544212
- 41 + 31544171 = 31544212
- 59 + 31544153 = 31544212
- 113 + 31544099 = 31544212
- 173 + 31544039 = 31544212
- 179 + 31544033 = 31544212
- 191 + 31544021 = 31544212
Showing the first eight; more decompositions exist.
