Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015284, here are decompositions:

7 + 1015277 = 1015284
113 + 1015171 = 1015284
157 + 1015127 = 1015284
191 + 1015093 = 1015284
211 + 1015073 = 1015284
223 + 1015061 = 1015284
227 + 1015057 = 1015284
233 + 1015051 = 1015284

Showing the first eight; more decompositions exist.
