Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525974, here are decompositions:
- 17 + 31525957 = 31525974
- 23 + 31525951 = 31525974
- 47 + 31525927 = 31525974
- 61 + 31525913 = 31525974
- 71 + 31525903 = 31525974
- 83 + 31525891 = 31525974
- 157 + 31525817 = 31525974
- 163 + 31525811 = 31525974
Showing the first eight; more decompositions exist.
