Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2756, here are decompositions:

3 + 2753 = 2756
7 + 2749 = 2756
37 + 2719 = 2756
43 + 2713 = 2756
67 + 2689 = 2756
73 + 2683 = 2756
79 + 2677 = 2756
97 + 2659 = 2756

Showing the first eight; more decompositions exist.
