Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665716, here are decompositions:

13 + 8665703 = 8665716
67 + 8665649 = 8665716
83 + 8665633 = 8665716
97 + 8665619 = 8665716
113 + 8665603 = 8665716
149 + 8665567 = 8665716
173 + 8665543 = 8665716
307 + 8665409 = 8665716

Showing the first eight; more decompositions exist.
