Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7772, here are decompositions:

13 + 7759 = 7772
19 + 7753 = 7772
31 + 7741 = 7772
73 + 7699 = 7772
103 + 7669 = 7772
151 + 7621 = 7772
181 + 7591 = 7772
199 + 7573 = 7772

Showing the first eight; more decompositions exist.
