Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 776, here are decompositions:

3 + 773 = 776
7 + 769 = 776
19 + 757 = 776
37 + 739 = 776
43 + 733 = 776
67 + 709 = 776
103 + 673 = 776
157 + 619 = 776

Showing the first eight; more decompositions exist.
