Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019238, here are decompositions:

29 + 1019209 = 1019238
41 + 1019197 = 1019238
61 + 1019177 = 1019238
109 + 1019129 = 1019238
167 + 1019071 = 1019238
179 + 1019059 = 1019238
239 + 1018999 = 1019238
251 + 1018987 = 1019238

Showing the first eight; more decompositions exist.
