Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478180, here are decompositions:

11 + 478169 = 478180
23 + 478157 = 478180
41 + 478139 = 478180
113 + 478067 = 478180
179 + 478001 = 478180
233 + 477947 = 478180
239 + 477941 = 478180
281 + 477899 = 478180

Showing the first eight; more decompositions exist.
