Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525908, here are decompositions:
- 5 + 31525903 = 31525908
- 17 + 31525891 = 31525908
- 19 + 31525889 = 31525908
- 59 + 31525849 = 31525908
- 67 + 31525841 = 31525908
- 97 + 31525811 = 31525908
- 109 + 31525799 = 31525908
- 131 + 31525777 = 31525908
Showing the first eight; more decompositions exist.
