Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526040, here are decompositions:
- 19 + 31526021 = 31526040
- 59 + 31525981 = 31526040
- 83 + 31525957 = 31526040
- 89 + 31525951 = 31526040
- 113 + 31525927 = 31526040
- 127 + 31525913 = 31526040
- 131 + 31525909 = 31526040
- 137 + 31525903 = 31526040
Showing the first eight; more decompositions exist.
