Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525900, here are decompositions:
- 11 + 31525889 = 31525900
- 59 + 31525841 = 31525900
- 83 + 31525817 = 31525900
- 89 + 31525811 = 31525900
- 101 + 31525799 = 31525900
- 113 + 31525787 = 31525900
- 137 + 31525763 = 31525900
- 251 + 31525649 = 31525900
Showing the first eight; more decompositions exist.
