Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544248, here are decompositions:
- 41 + 31544207 = 31544248
- 59 + 31544189 = 31544248
- 149 + 31544099 = 31544248
- 191 + 31544057 = 31544248
- 227 + 31544021 = 31544248
- 251 + 31543997 = 31544248
- 257 + 31543991 = 31544248
- 269 + 31543979 = 31544248
Showing the first eight; more decompositions exist.
