Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018822, here are decompositions:

5 + 1018817 = 1018822
11 + 1018811 = 1018822
53 + 1018769 = 1018822
59 + 1018763 = 1018822
89 + 1018733 = 1018822
113 + 1018709 = 1018822
149 + 1018673 = 1018822
173 + 1018649 = 1018822

Showing the first eight; more decompositions exist.
