Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019646, here are decompositions:

7 + 1019639 = 1019646
29 + 1019617 = 1019646
83 + 1019563 = 1019646
97 + 1019549 = 1019646
109 + 1019537 = 1019646
113 + 1019533 = 1019646
137 + 1019509 = 1019646
167 + 1019479 = 1019646

Showing the first eight; more decompositions exist.
