Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544244, here are decompositions:
- 23 + 31544221 = 31544244
- 31 + 31544213 = 31544244
- 37 + 31544207 = 31544244
- 73 + 31544171 = 31544244
- 113 + 31544131 = 31544244
- 167 + 31544077 = 31544244
- 191 + 31544053 = 31544244
- 211 + 31544033 = 31544244
Showing the first eight; more decompositions exist.
