Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717628, here are decompositions:

5 + 8717623 = 8717628
37 + 8717591 = 8717628
71 + 8717557 = 8717628
97 + 8717531 = 8717628
107 + 8717521 = 8717628
137 + 8717491 = 8717628
239 + 8717389 = 8717628
389 + 8717239 = 8717628

Showing the first eight; more decompositions exist.
