Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42256, here are decompositions:

17 + 42239 = 42256
29 + 42227 = 42256
47 + 42209 = 42256
59 + 42197 = 42256
167 + 42089 = 42256
173 + 42083 = 42256
233 + 42023 = 42256
239 + 42017 = 42256

Showing the first eight; more decompositions exist.
