Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038142, here are decompositions:

23 + 1038119 = 1038142
101 + 1038041 = 1038142
113 + 1038029 = 1038142
179 + 1037963 = 1038142
239 + 1037903 = 1038142
263 + 1037879 = 1038142
269 + 1037873 = 1038142
311 + 1037831 = 1038142

Showing the first eight; more decompositions exist.
