Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717528, here are decompositions:

7 + 8717521 = 8717528
19 + 8717509 = 8717528
37 + 8717491 = 8717528
139 + 8717389 = 8717528
199 + 8717329 = 8717528
241 + 8717287 = 8717528
397 + 8717131 = 8717528
409 + 8717119 = 8717528

Showing the first eight; more decompositions exist.
