Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938658, here are decompositions:

41 + 938617 = 938658
47 + 938611 = 938658
67 + 938591 = 938658
89 + 938569 = 938658
151 + 938507 = 938658
167 + 938491 = 938658
199 + 938459 = 938658
211 + 938447 = 938658

Showing the first eight; more decompositions exist.
