Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526146, here are decompositions:
- 5 + 31526141 = 31526146
- 59 + 31526087 = 31526146
- 83 + 31526063 = 31526146
- 89 + 31526057 = 31526146
- 227 + 31525919 = 31526146
- 233 + 31525913 = 31526146
- 257 + 31525889 = 31526146
- 347 + 31525799 = 31526146
Showing the first eight; more decompositions exist.
