Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018816, here are decompositions:

3 + 1018813 = 1018816
5 + 1018811 = 1018816
47 + 1018769 = 1018816
53 + 1018763 = 1018816
83 + 1018733 = 1018816
107 + 1018709 = 1018816
137 + 1018679 = 1018816
167 + 1018649 = 1018816

Showing the first eight; more decompositions exist.
