Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11730, here are decompositions:

11 + 11719 = 11730
13 + 11717 = 11730
29 + 11701 = 11730
31 + 11699 = 11730
41 + 11689 = 11730
53 + 11677 = 11730
73 + 11657 = 11730
97 + 11633 = 11730

Showing the first eight; more decompositions exist.
