Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2776, here are decompositions:

23 + 2753 = 2776
47 + 2729 = 2776
83 + 2693 = 2776
89 + 2687 = 2776
113 + 2663 = 2776
167 + 2609 = 2776
197 + 2579 = 2776
227 + 2549 = 2776

Showing the first eight; more decompositions exist.
