Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87730, here are decompositions:

11 + 87719 = 87730
29 + 87701 = 87730
47 + 87683 = 87730
59 + 87671 = 87730
89 + 87641 = 87730
101 + 87629 = 87730
107 + 87623 = 87730
173 + 87557 = 87730

Showing the first eight; more decompositions exist.
