Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544440, here are decompositions:
- 23 + 31544417 = 31544440
- 47 + 31544393 = 31544440
- 227 + 31544213 = 31544440
- 233 + 31544207 = 31544440
- 251 + 31544189 = 31544440
- 269 + 31544171 = 31544440
- 383 + 31544057 = 31544440
- 401 + 31544039 = 31544440
Showing the first eight; more decompositions exist.
