Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525912, here are decompositions:
- 3 + 31525909 = 31525912
- 23 + 31525889 = 31525912
- 71 + 31525841 = 31525912
- 101 + 31525811 = 31525912
- 113 + 31525799 = 31525912
- 149 + 31525763 = 31525912
- 263 + 31525649 = 31525912
- 311 + 31525601 = 31525912
Showing the first eight; more decompositions exist.
