Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027638, here are decompositions:

41 + 1027597 = 1027638
47 + 1027591 = 1027638
71 + 1027567 = 1027638
89 + 1027549 = 1027638
149 + 1027489 = 1027638
151 + 1027487 = 1027638
167 + 1027471 = 1027638
179 + 1027459 = 1027638

Showing the first eight; more decompositions exist.
