Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78256, here are decompositions:

23 + 78233 = 78256
53 + 78203 = 78256
83 + 78173 = 78256
89 + 78167 = 78256
197 + 78059 = 78256
239 + 78017 = 78256
257 + 77999 = 78256
389 + 77867 = 78256

Showing the first eight; more decompositions exist.
