Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938826, here are decompositions:

19 + 938807 = 938826
23 + 938803 = 938826
79 + 938747 = 938826
113 + 938713 = 938826
149 + 938677 = 938826
167 + 938659 = 938826
257 + 938569 = 938826
263 + 938563 = 938826

Showing the first eight; more decompositions exist.
