Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8770, here are decompositions:

17 + 8753 = 8770
23 + 8747 = 8770
29 + 8741 = 8770
71 + 8699 = 8770
89 + 8681 = 8770
101 + 8669 = 8770
107 + 8663 = 8770
173 + 8597 = 8770

Showing the first eight; more decompositions exist.
