Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015788, here are decompositions:

19 + 1015769 = 1015788
41 + 1015747 = 1015788
61 + 1015727 = 1015788
79 + 1015709 = 1015788
97 + 1015691 = 1015788
127 + 1015661 = 1015788
227 + 1015561 = 1015788
229 + 1015559 = 1015788

Showing the first eight; more decompositions exist.
