Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659620, here are decompositions:

19 + 8659601 = 8659620
31 + 8659589 = 8659620
61 + 8659559 = 8659620
83 + 8659537 = 8659620
89 + 8659531 = 8659620
107 + 8659513 = 8659620
149 + 8659471 = 8659620
157 + 8659463 = 8659620

Showing the first eight; more decompositions exist.
