Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015516, here are decompositions:

17 + 1015499 = 1015516
53 + 1015463 = 1015516
83 + 1015433 = 1015516
107 + 1015409 = 1015516
113 + 1015403 = 1015516
149 + 1015367 = 1015516
167 + 1015349 = 1015516
239 + 1015277 = 1015516

Showing the first eight; more decompositions exist.
