Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478522, here are decompositions:

29 + 478493 = 478522
41 + 478481 = 478522
71 + 478451 = 478522
89 + 478433 = 478522
101 + 478421 = 478522
131 + 478391 = 478522
179 + 478343 = 478522
251 + 478271 = 478522

Showing the first eight; more decompositions exist.
