Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525960, here are decompositions:
- 3 + 31525957 = 31525960
- 41 + 31525919 = 31525960
- 47 + 31525913 = 31525960
- 71 + 31525889 = 31525960
- 149 + 31525811 = 31525960
- 173 + 31525787 = 31525960
- 197 + 31525763 = 31525960
- 311 + 31525649 = 31525960
Showing the first eight; more decompositions exist.
