Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015942, here are decompositions:

23 + 1015919 = 1015942
29 + 1015913 = 1015942
71 + 1015871 = 1015942
89 + 1015853 = 1015942
113 + 1015829 = 1015942
173 + 1015769 = 1015942
233 + 1015709 = 1015942
251 + 1015691 = 1015942

Showing the first eight; more decompositions exist.
