Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938636, here are decompositions:

19 + 938617 = 938636
67 + 938569 = 938636
73 + 938563 = 938636
103 + 938533 = 938636
199 + 938437 = 938636
277 + 938359 = 938636
313 + 938323 = 938636
373 + 938263 = 938636

Showing the first eight; more decompositions exist.
