Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018662, here are decompositions:

11 + 1018651 = 1018662
13 + 1018649 = 1018662
19 + 1018643 = 1018662
41 + 1018621 = 1018662
79 + 1018583 = 1018662
103 + 1018559 = 1018662
149 + 1018513 = 1018662
173 + 1018489 = 1018662

Showing the first eight; more decompositions exist.
