Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938518, here are decompositions:

11 + 938507 = 938518
59 + 938459 = 938518
71 + 938447 = 938518
131 + 938387 = 938518
149 + 938369 = 938518
167 + 938351 = 938518
239 + 938279 = 938518
311 + 938207 = 938518

Showing the first eight; more decompositions exist.
