Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526172, here are decompositions:
- 31 + 31526141 = 31526172
- 89 + 31526083 = 31526172
- 103 + 31526069 = 31526172
- 109 + 31526063 = 31526172
- 151 + 31526021 = 31526172
- 191 + 31525981 = 31526172
- 263 + 31525909 = 31526172
- 269 + 31525903 = 31526172
Showing the first eight; more decompositions exist.
