Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15712, here are decompositions:

29 + 15683 = 15712
41 + 15671 = 15712
71 + 15641 = 15712
83 + 15629 = 15712
131 + 15581 = 15712
239 + 15473 = 15712
251 + 15461 = 15712
269 + 15443 = 15712

Showing the first eight; more decompositions exist.
