Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15682, here are decompositions:

3 + 15679 = 15682
11 + 15671 = 15682
41 + 15641 = 15682
53 + 15629 = 15682
101 + 15581 = 15682
113 + 15569 = 15682
131 + 15551 = 15682
239 + 15443 = 15682

Showing the first eight; more decompositions exist.
