Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525980, here are decompositions:
- 23 + 31525957 = 31525980
- 29 + 31525951 = 31525980
- 53 + 31525927 = 31525980
- 61 + 31525919 = 31525980
- 67 + 31525913 = 31525980
- 71 + 31525909 = 31525980
- 89 + 31525891 = 31525980
- 131 + 31525849 = 31525980
Showing the first eight; more decompositions exist.
