Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015642, here are decompositions:

41 + 1015601 = 1015642
71 + 1015571 = 1015642
83 + 1015559 = 1015642
101 + 1015541 = 1015642
179 + 1015463 = 1015642
191 + 1015451 = 1015642
233 + 1015409 = 1015642
239 + 1015403 = 1015642

Showing the first eight; more decompositions exist.
