Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019630, here are decompositions:

13 + 1019617 = 1019630
67 + 1019563 = 1019630
97 + 1019533 = 1019630
127 + 1019503 = 1019630
151 + 1019479 = 1019630
163 + 1019467 = 1019630
181 + 1019449 = 1019630
277 + 1019353 = 1019630

Showing the first eight; more decompositions exist.
