Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689620, here are decompositions:

11 + 8689609 = 8689620
29 + 8689591 = 8689620
47 + 8689573 = 8689620
67 + 8689553 = 8689620
83 + 8689537 = 8689620
127 + 8689493 = 8689620
131 + 8689489 = 8689620
139 + 8689481 = 8689620

Showing the first eight; more decompositions exist.
