Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15716, here are decompositions:

37 + 15679 = 15716
67 + 15649 = 15716
73 + 15643 = 15716
97 + 15619 = 15716
109 + 15607 = 15716
157 + 15559 = 15716
223 + 15493 = 15716
277 + 15439 = 15716

Showing the first eight; more decompositions exist.
