Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938526, here are decompositions:

19 + 938507 = 938526
67 + 938459 = 938526
73 + 938453 = 938526
79 + 938447 = 938526
89 + 938437 = 938526
139 + 938387 = 938526
157 + 938369 = 938526
167 + 938359 = 938526

Showing the first eight; more decompositions exist.
