Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478132, here are decompositions:

3 + 478129 = 478132
131 + 478001 = 478132
191 + 477941 = 478132
233 + 477899 = 478132
251 + 477881 = 478132
269 + 477863 = 478132
293 + 477839 = 478132
311 + 477821 = 478132

Showing the first eight; more decompositions exist.
