Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713620, here are decompositions:

17 + 8713603 = 8713620
29 + 8713591 = 8713620
37 + 8713583 = 8713620
43 + 8713577 = 8713620
53 + 8713567 = 8713620
67 + 8713553 = 8713620
73 + 8713547 = 8713620
89 + 8713531 = 8713620

Showing the first eight; more decompositions exist.
