Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718, here are decompositions:

5 + 8713 = 8718
11 + 8707 = 8718
19 + 8699 = 8718
29 + 8689 = 8718
37 + 8681 = 8718
41 + 8677 = 8718
71 + 8647 = 8718
89 + 8629 = 8718

Showing the first eight; more decompositions exist.
