Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15776, here are decompositions:

3 + 15773 = 15776
37 + 15739 = 15776
43 + 15733 = 15776
97 + 15679 = 15776
109 + 15667 = 15776
127 + 15649 = 15776
157 + 15619 = 15776
193 + 15583 = 15776

Showing the first eight; more decompositions exist.
