Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525902, here are decompositions:
- 11 + 31525891 = 31525902
- 13 + 31525889 = 31525902
- 53 + 31525849 = 31525902
- 61 + 31525841 = 31525902
- 103 + 31525799 = 31525902
- 131 + 31525771 = 31525902
- 139 + 31525763 = 31525902
- 179 + 31525723 = 31525902
Showing the first eight; more decompositions exist.
