Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017816, here are decompositions:

17 + 1017799 = 1017816
29 + 1017787 = 1017816
67 + 1017749 = 1017816
97 + 1017719 = 1017816
103 + 1017713 = 1017816
113 + 1017703 = 1017816
167 + 1017649 = 1017816
193 + 1017623 = 1017816

Showing the first eight; more decompositions exist.
