Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938864, here are decompositions:

7 + 938857 = 938864
37 + 938827 = 938864
61 + 938803 = 938864
103 + 938761 = 938864
151 + 938713 = 938864
331 + 938533 = 938864
373 + 938491 = 938864
523 + 938341 = 938864

Showing the first eight; more decompositions exist.
