Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526128, here are decompositions:
- 41 + 31526087 = 31526128
- 59 + 31526069 = 31526128
- 71 + 31526057 = 31526128
- 107 + 31526021 = 31526128
- 239 + 31525889 = 31526128
- 311 + 31525817 = 31526128
- 317 + 31525811 = 31526128
- 479 + 31525649 = 31526128
Showing the first eight; more decompositions exist.
