Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2774, here are decompositions:

7 + 2767 = 2774
43 + 2731 = 2774
61 + 2713 = 2774
67 + 2707 = 2774
97 + 2677 = 2774
103 + 2671 = 2774
127 + 2647 = 2774
157 + 2617 = 2774

Showing the first eight; more decompositions exist.
