Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478492, here are decompositions:

11 + 478481 = 478492
41 + 478451 = 478492
59 + 478433 = 478492
71 + 478421 = 478492
89 + 478403 = 478492
101 + 478391 = 478492
149 + 478343 = 478492
233 + 478259 = 478492

Showing the first eight; more decompositions exist.
