Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665620, here are decompositions:

17 + 8665603 = 8665620
37 + 8665583 = 8665620
53 + 8665567 = 8665620
59 + 8665561 = 8665620
79 + 8665541 = 8665620
149 + 8665471 = 8665620
151 + 8665469 = 8665620
179 + 8665441 = 8665620

Showing the first eight; more decompositions exist.
