Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42718, here are decompositions:

17 + 42701 = 42718
29 + 42689 = 42718
41 + 42677 = 42718
107 + 42611 = 42718
149 + 42569 = 42718
227 + 42491 = 42718
251 + 42467 = 42718
257 + 42461 = 42718

Showing the first eight; more decompositions exist.
