Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27768, here are decompositions:

5 + 27763 = 27768
17 + 27751 = 27768
19 + 27749 = 27768
29 + 27739 = 27768
31 + 27737 = 27768
67 + 27701 = 27768
71 + 27697 = 27768
79 + 27689 = 27768

Showing the first eight; more decompositions exist.
