Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525860, here are decompositions:
- 11 + 31525849 = 31525860
- 19 + 31525841 = 31525860
- 43 + 31525817 = 31525860
- 61 + 31525799 = 31525860
- 73 + 31525787 = 31525860
- 83 + 31525777 = 31525860
- 89 + 31525771 = 31525860
- 97 + 31525763 = 31525860
Showing the first eight; more decompositions exist.
