Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746816, here are decompositions:

3 + 8746813 = 8746816
5 + 8746811 = 8746816
17 + 8746799 = 8746816
59 + 8746757 = 8746816
83 + 8746733 = 8746816
107 + 8746709 = 8746816
137 + 8746679 = 8746816
179 + 8746637 = 8746816

Showing the first eight; more decompositions exist.
