Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478072, here are decompositions:

3 + 478069 = 478072
5 + 478067 = 478072
71 + 478001 = 478072
131 + 477941 = 478072
173 + 477899 = 478072
191 + 477881 = 478072
233 + 477839 = 478072
251 + 477821 = 478072

Showing the first eight; more decompositions exist.
