Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2772, here are decompositions:

5 + 2767 = 2772
19 + 2753 = 2772
23 + 2749 = 2772
31 + 2741 = 2772
41 + 2731 = 2772
43 + 2729 = 2772
53 + 2719 = 2772
59 + 2713 = 2772

Showing the first eight; more decompositions exist.
