Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015678, here are decompositions:

17 + 1015661 = 1015678
107 + 1015571 = 1015678
137 + 1015541 = 1015678
179 + 1015499 = 1015678
197 + 1015481 = 1015678
227 + 1015451 = 1015678
269 + 1015409 = 1015678
311 + 1015367 = 1015678

Showing the first eight; more decompositions exist.
