Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528104, here are decompositions:
- 11 + 31528093 = 31528104
- 37 + 31528067 = 31528104
- 67 + 31528037 = 31528104
- 103 + 31528001 = 31528104
- 107 + 31527997 = 31528104
- 137 + 31527967 = 31528104
- 163 + 31527941 = 31528104
- 173 + 31527931 = 31528104
Showing the first eight; more decompositions exist.
