Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018656, here are decompositions:

5 + 1018651 = 1018656
7 + 1018649 = 1018656
13 + 1018643 = 1018656
43 + 1018613 = 1018656
73 + 1018583 = 1018656
97 + 1018559 = 1018656
113 + 1018543 = 1018656
167 + 1018489 = 1018656

Showing the first eight; more decompositions exist.
