Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019572, here are decompositions:

23 + 1019549 = 1019572
41 + 1019531 = 1019572
101 + 1019471 = 1019572
149 + 1019423 = 1019572
173 + 1019399 = 1019572
233 + 1019339 = 1019572
311 + 1019261 = 1019572
443 + 1019129 = 1019572

Showing the first eight; more decompositions exist.
