Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019628, here are decompositions:

11 + 1019617 = 1019628
79 + 1019549 = 1019628
97 + 1019531 = 1019628
149 + 1019479 = 1019628
157 + 1019471 = 1019628
179 + 1019449 = 1019628
229 + 1019399 = 1019628
251 + 1019377 = 1019628

Showing the first eight; more decompositions exist.
