Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700, here are decompositions:

7 + 8693 = 8700
11 + 8689 = 8700
19 + 8681 = 8700
23 + 8677 = 8700
31 + 8669 = 8700
37 + 8663 = 8700
53 + 8647 = 8700
59 + 8641 = 8700

Showing the first eight; more decompositions exist.
