Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479666, here are decompositions:

37 + 479629 = 479666
43 + 479623 = 479666
67 + 479599 = 479666
73 + 479593 = 479666
97 + 479569 = 479666
157 + 479509 = 479666
193 + 479473 = 479666
349 + 479317 = 479666

Showing the first eight; more decompositions exist.
