Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019042, here are decompositions:

19 + 1019023 = 1019042
43 + 1018999 = 1019042
61 + 1018981 = 1019042
139 + 1018903 = 1019042
163 + 1018879 = 1019042
229 + 1018813 = 1019042
313 + 1018729 = 1019042
331 + 1018711 = 1019042

Showing the first eight; more decompositions exist.
