Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15656, here are decompositions:

7 + 15649 = 15656
13 + 15643 = 15656
37 + 15619 = 15656
73 + 15583 = 15656
97 + 15559 = 15656
163 + 15493 = 15656
229 + 15427 = 15656
283 + 15373 = 15656

Showing the first eight; more decompositions exist.
