Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015918, here are decompositions:

5 + 1015913 = 1015918
11 + 1015907 = 1015918
41 + 1015877 = 1015918
47 + 1015871 = 1015918
89 + 1015829 = 1015918
149 + 1015769 = 1015918
179 + 1015739 = 1015918
191 + 1015727 = 1015918

Showing the first eight; more decompositions exist.
