Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015278, here are decompositions:

71 + 1015207 = 1015278
79 + 1015199 = 1015278
107 + 1015171 = 1015278
139 + 1015139 = 1015278
151 + 1015127 = 1015278
181 + 1015097 = 1015278
197 + 1015081 = 1015278
211 + 1015067 = 1015278

Showing the first eight; more decompositions exist.
