Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015286, here are decompositions:

79 + 1015207 = 1015286
127 + 1015159 = 1015286
163 + 1015123 = 1015286
193 + 1015093 = 1015286
229 + 1015057 = 1015286
277 + 1015009 = 1015286
313 + 1014973 = 1015286
379 + 1014907 = 1015286

Showing the first eight; more decompositions exist.
