Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005816, here are decompositions:

107 + 1005709 = 1005816
137 + 1005679 = 1005816
139 + 1005677 = 1005816
173 + 1005643 = 1005816
179 + 1005637 = 1005816
197 + 1005619 = 1005816
199 + 1005617 = 1005816
223 + 1005593 = 1005816

Showing the first eight; more decompositions exist.
