Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525920, here are decompositions:
- 7 + 31525913 = 31525920
- 11 + 31525909 = 31525920
- 17 + 31525903 = 31525920
- 29 + 31525891 = 31525920
- 31 + 31525889 = 31525920
- 71 + 31525849 = 31525920
- 79 + 31525841 = 31525920
- 103 + 31525817 = 31525920
Showing the first eight; more decompositions exist.
