Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019658, here are decompositions:

11 + 1019647 = 1019658
19 + 1019639 = 1019658
41 + 1019617 = 1019658
109 + 1019549 = 1019658
127 + 1019531 = 1019658
149 + 1019509 = 1019658
179 + 1019479 = 1019658
191 + 1019467 = 1019658

Showing the first eight; more decompositions exist.
