Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78566, here are decompositions:
- 13 + 78553 = 78566
- 79 + 78487 = 78566
- 127 + 78439 = 78566
- 139 + 78427 = 78566
- 199 + 78367 = 78566
- 283 + 78283 = 78566
- 307 + 78259 = 78566
- 337 + 78229 = 78566
Showing the first eight; more decompositions exist.
