Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2766, here are decompositions:

13 + 2753 = 2766
17 + 2749 = 2766
37 + 2729 = 2766
47 + 2719 = 2766
53 + 2713 = 2766
59 + 2707 = 2766
67 + 2699 = 2766
73 + 2693 = 2766

Showing the first eight; more decompositions exist.
