Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15662, here are decompositions:

13 + 15649 = 15662
19 + 15643 = 15662
43 + 15619 = 15662
61 + 15601 = 15662
79 + 15583 = 15662
103 + 15559 = 15662
151 + 15511 = 15662
211 + 15451 = 15662

Showing the first eight; more decompositions exist.
