Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102776, here are decompositions:

7 + 102769 = 102776
13 + 102763 = 102776
97 + 102679 = 102776
103 + 102673 = 102776
109 + 102667 = 102776
229 + 102547 = 102776
277 + 102499 = 102776
367 + 102409 = 102776

Showing the first eight; more decompositions exist.
