Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532910, here are decompositions:
- 11 + 31532899 = 31532910
- 29 + 31532881 = 31532910
- 37 + 31532873 = 31532910
- 43 + 31532867 = 31532910
- 47 + 31532863 = 31532910
- 173 + 31532737 = 31532910
- 223 + 31532687 = 31532910
- 251 + 31532659 = 31532910
Showing the first eight; more decompositions exist.
