Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525928, here are decompositions:
- 19 + 31525909 = 31525928
- 37 + 31525891 = 31525928
- 79 + 31525849 = 31525928
- 151 + 31525777 = 31525928
- 157 + 31525771 = 31525928
- 211 + 31525717 = 31525928
- 229 + 31525699 = 31525928
- 241 + 31525687 = 31525928
Showing the first eight; more decompositions exist.
