Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019512, here are decompositions:

3 + 1019509 = 1019512
41 + 1019471 = 1019512
59 + 1019453 = 1019512
89 + 1019423 = 1019512
101 + 1019411 = 1019512
113 + 1019399 = 1019512
173 + 1019339 = 1019512
239 + 1019273 = 1019512

Showing the first eight; more decompositions exist.
