Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017638, here are decompositions:

31 + 1017607 = 1017638
79 + 1017559 = 1017638
157 + 1017481 = 1017638
199 + 1017439 = 1017638
277 + 1017361 = 1017638
331 + 1017307 = 1017638
337 + 1017301 = 1017638
439 + 1017199 = 1017638

Showing the first eight; more decompositions exist.
