Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544216, here are decompositions:
- 3 + 31544213 = 31544216
- 37 + 31544179 = 31544216
- 127 + 31544089 = 31544216
- 139 + 31544077 = 31544216
- 163 + 31544053 = 31544216
- 229 + 31543987 = 31544216
- 313 + 31543903 = 31544216
- 373 + 31543843 = 31544216
Showing the first eight; more decompositions exist.
