Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688620, here are decompositions:

7 + 8688613 = 8688620
13 + 8688607 = 8688620
19 + 8688601 = 8688620
37 + 8688583 = 8688620
43 + 8688577 = 8688620
67 + 8688553 = 8688620
151 + 8688469 = 8688620
211 + 8688409 = 8688620

Showing the first eight; more decompositions exist.
