Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015386, here are decompositions:

17 + 1015369 = 1015386
19 + 1015367 = 1015386
23 + 1015363 = 1015386
37 + 1015349 = 1015386
109 + 1015277 = 1015386
179 + 1015207 = 1015386
223 + 1015163 = 1015386
227 + 1015159 = 1015386

Showing the first eight; more decompositions exist.
