Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27780, here are decompositions:

7 + 27773 = 27780
13 + 27767 = 27780
17 + 27763 = 27780
29 + 27751 = 27780
31 + 27749 = 27780
37 + 27743 = 27780
41 + 27739 = 27780
43 + 27737 = 27780

Showing the first eight; more decompositions exist.
