Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478732, here are decompositions:

3 + 478729 = 478732
5 + 478727 = 478732
53 + 478679 = 478732
101 + 478631 = 478732
239 + 478493 = 478732
251 + 478481 = 478732
281 + 478451 = 478732
311 + 478421 = 478732

Showing the first eight; more decompositions exist.
