Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730, here are decompositions:

11 + 8719 = 8730
17 + 8713 = 8730
23 + 8707 = 8730
31 + 8699 = 8730
37 + 8693 = 8730
41 + 8689 = 8730
53 + 8677 = 8730
61 + 8669 = 8730

Showing the first eight; more decompositions exist.
