Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525944, here are decompositions:
- 17 + 31525927 = 31525944
- 31 + 31525913 = 31525944
- 41 + 31525903 = 31525944
- 53 + 31525891 = 31525944
- 103 + 31525841 = 31525944
- 127 + 31525817 = 31525944
- 157 + 31525787 = 31525944
- 167 + 31525777 = 31525944
Showing the first eight; more decompositions exist.
