Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525894, here are decompositions:
- 3 + 31525891 = 31525894
- 5 + 31525889 = 31525894
- 53 + 31525841 = 31525894
- 83 + 31525811 = 31525894
- 107 + 31525787 = 31525894
- 131 + 31525763 = 31525894
- 293 + 31525601 = 31525894
- 563 + 31525331 = 31525894
Showing the first eight; more decompositions exist.
