Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27770, here are decompositions:

3 + 27767 = 27770
7 + 27763 = 27770
19 + 27751 = 27770
31 + 27739 = 27770
37 + 27733 = 27770
73 + 27697 = 27770
79 + 27691 = 27770
97 + 27673 = 27770

Showing the first eight; more decompositions exist.
