Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478518, here are decompositions:

37 + 478481 = 478518
59 + 478459 = 478518
67 + 478451 = 478518
97 + 478421 = 478518
101 + 478417 = 478518
107 + 478411 = 478518
127 + 478391 = 478518
167 + 478351 = 478518

Showing the first eight; more decompositions exist.
