Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938490, here are decompositions:

31 + 938459 = 938490
37 + 938453 = 938490
43 + 938447 = 938490
53 + 938437 = 938490
97 + 938393 = 938490
103 + 938387 = 938490
131 + 938359 = 938490
139 + 938351 = 938490

Showing the first eight; more decompositions exist.
