Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938458, here are decompositions:

5 + 938453 = 938458
11 + 938447 = 938458
71 + 938387 = 938458
89 + 938369 = 938458
107 + 938351 = 938458
149 + 938309 = 938458
179 + 938279 = 938458
239 + 938219 = 938458

Showing the first eight; more decompositions exist.
