Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74278, here are decompositions:

47 + 74231 = 74278
59 + 74219 = 74278
89 + 74189 = 74278
101 + 74177 = 74278
179 + 74099 = 74278
227 + 74051 = 74278
251 + 74027 = 74278
257 + 74021 = 74278

Showing the first eight; more decompositions exist.
