Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019494, here are decompositions:

23 + 1019471 = 1019494
41 + 1019453 = 1019494
71 + 1019423 = 1019494
83 + 1019411 = 1019494
137 + 1019357 = 1019494
197 + 1019297 = 1019494
227 + 1019267 = 1019494
233 + 1019261 = 1019494

Showing the first eight; more decompositions exist.
