Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2730, here are decompositions:

11 + 2719 = 2730
17 + 2713 = 2730
19 + 2711 = 2730
23 + 2707 = 2730
31 + 2699 = 2730
37 + 2693 = 2730
41 + 2689 = 2730
43 + 2687 = 2730

Showing the first eight; more decompositions exist.
