Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525886, here are decompositions:
- 37 + 31525849 = 31525886
- 103 + 31525783 = 31525886
- 109 + 31525777 = 31525886
- 163 + 31525723 = 31525886
- 199 + 31525687 = 31525886
- 229 + 31525657 = 31525886
- 277 + 31525609 = 31525886
- 283 + 31525603 = 31525886
Showing the first eight; more decompositions exist.
