Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015878, here are decompositions:

7 + 1015871 = 1015878
109 + 1015769 = 1015878
131 + 1015747 = 1015878
139 + 1015739 = 1015878
151 + 1015727 = 1015878
181 + 1015697 = 1015878
251 + 1015627 = 1015878
277 + 1015601 = 1015878

Showing the first eight; more decompositions exist.
