Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525992, here are decompositions:
- 11 + 31525981 = 31525992
- 41 + 31525951 = 31525992
- 73 + 31525919 = 31525992
- 79 + 31525913 = 31525992
- 83 + 31525909 = 31525992
- 89 + 31525903 = 31525992
- 101 + 31525891 = 31525992
- 103 + 31525889 = 31525992
Showing the first eight; more decompositions exist.
