Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57278, here are decompositions:
- 7 + 57271 = 57278
- 19 + 57259 = 57278
- 37 + 57241 = 57278
- 139 + 57139 = 57278
- 181 + 57097 = 57278
- 241 + 57037 = 57278
- 337 + 56941 = 57278
- 349 + 56929 = 57278
Showing the first eight; more decompositions exist.
