Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537164, here are decompositions:
- 11 + 31537153 = 31537164
- 13 + 31537151 = 31537164
- 17 + 31537147 = 31537164
- 31 + 31537133 = 31537164
- 37 + 31537127 = 31537164
- 67 + 31537097 = 31537164
- 137 + 31537027 = 31537164
- 163 + 31537001 = 31537164
Showing the first eight; more decompositions exist.
