Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27776, here are decompositions:

3 + 27773 = 27776
13 + 27763 = 27776
37 + 27739 = 27776
43 + 27733 = 27776
79 + 27697 = 27776
103 + 27673 = 27776
193 + 27583 = 27776
349 + 27427 = 27776

Showing the first eight; more decompositions exist.
