Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019680, here are decompositions:

17 + 1019663 = 1019680
23 + 1019657 = 1019680
41 + 1019639 = 1019680
131 + 1019549 = 1019680
149 + 1019531 = 1019680
227 + 1019453 = 1019680
257 + 1019423 = 1019680
269 + 1019411 = 1019680

Showing the first eight; more decompositions exist.
