Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526166, here are decompositions:
- 79 + 31526087 = 31526166
- 83 + 31526083 = 31526166
- 97 + 31526069 = 31526166
- 103 + 31526063 = 31526166
- 109 + 31526057 = 31526166
- 239 + 31525927 = 31526166
- 257 + 31525909 = 31526166
- 263 + 31525903 = 31526166
Showing the first eight; more decompositions exist.
