Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15714, here are decompositions:

31 + 15683 = 15714
43 + 15671 = 15714
47 + 15667 = 15714
53 + 15661 = 15714
67 + 15647 = 15714
71 + 15643 = 15714
73 + 15641 = 15714
107 + 15607 = 15714

Showing the first eight; more decompositions exist.
