Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019250, here are decompositions:

13 + 1019237 = 1019250
41 + 1019209 = 1019250
53 + 1019197 = 1019250
73 + 1019177 = 1019250
131 + 1019119 = 1019250
157 + 1019093 = 1019250
173 + 1019077 = 1019250
179 + 1019071 = 1019250

Showing the first eight; more decompositions exist.
