Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478120, here are decompositions:

53 + 478067 = 478120
173 + 477947 = 478120
179 + 477941 = 478120
239 + 477881 = 478120
257 + 477863 = 478120
263 + 477857 = 478120
281 + 477839 = 478120
311 + 477809 = 478120

Showing the first eight; more decompositions exist.
