Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479538, here are decompositions:

5 + 479533 = 479538
29 + 479509 = 479538
41 + 479497 = 479538
97 + 479441 = 479538
107 + 479431 = 479538
109 + 479429 = 479538
151 + 479387 = 479538
167 + 479371 = 479538

Showing the first eight; more decompositions exist.
