Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938642, here are decompositions:

31 + 938611 = 938642
73 + 938569 = 938642
79 + 938563 = 938642
109 + 938533 = 938642
151 + 938491 = 938642
283 + 938359 = 938642
349 + 938293 = 938642
379 + 938263 = 938642

Showing the first eight; more decompositions exist.
