Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671620, here are decompositions:

31 + 8671589 = 8671620
37 + 8671583 = 8671620
47 + 8671573 = 8671620
71 + 8671549 = 8671620
101 + 8671519 = 8671620
103 + 8671517 = 8671620
109 + 8671511 = 8671620
149 + 8671471 = 8671620

Showing the first eight; more decompositions exist.
