Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019566, here are decompositions:

3 + 1019563 = 1019566
17 + 1019549 = 1019566
29 + 1019537 = 1019566
113 + 1019453 = 1019566
167 + 1019399 = 1019566
227 + 1019339 = 1019566
269 + 1019297 = 1019566
293 + 1019273 = 1019566

Showing the first eight; more decompositions exist.
