Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27790, here are decompositions:

11 + 27779 = 27790
17 + 27773 = 27790
23 + 27767 = 27790
41 + 27749 = 27790
47 + 27743 = 27790
53 + 27737 = 27790
89 + 27701 = 27790
101 + 27689 = 27790

Showing the first eight; more decompositions exist.
