Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015786, here are decompositions:

17 + 1015769 = 1015786
47 + 1015739 = 1015786
59 + 1015727 = 1015786
89 + 1015697 = 1015786
227 + 1015559 = 1015786
263 + 1015523 = 1015786
269 + 1015517 = 1015786
353 + 1015433 = 1015786

Showing the first eight; more decompositions exist.
