Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757816, here are decompositions:

7 + 8757809 = 8757816
17 + 8757799 = 8757816
47 + 8757769 = 8757816
59 + 8757757 = 8757816
97 + 8757719 = 8757816
103 + 8757713 = 8757816
157 + 8757659 = 8757816
173 + 8757643 = 8757816

Showing the first eight; more decompositions exist.
