Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525988, here are decompositions:
- 7 + 31525981 = 31525988
- 31 + 31525957 = 31525988
- 37 + 31525951 = 31525988
- 61 + 31525927 = 31525988
- 79 + 31525909 = 31525988
- 97 + 31525891 = 31525988
- 139 + 31525849 = 31525988
- 211 + 31525777 = 31525988
Showing the first eight; more decompositions exist.
