Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015866, here are decompositions:

13 + 1015853 = 1015866
23 + 1015843 = 1015866
37 + 1015829 = 1015866
43 + 1015823 = 1015866
53 + 1015813 = 1015866
97 + 1015769 = 1015866
113 + 1015753 = 1015866
127 + 1015739 = 1015866

Showing the first eight; more decompositions exist.
