Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938528, here are decompositions:

37 + 938491 = 938528
181 + 938347 = 938528
271 + 938257 = 938528
277 + 938251 = 938528
421 + 938107 = 938528
439 + 938089 = 938528
457 + 938071 = 938528
601 + 937927 = 938528

Showing the first eight; more decompositions exist.
