Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15724, here are decompositions:

41 + 15683 = 15724
53 + 15671 = 15724
83 + 15641 = 15724
173 + 15551 = 15724
197 + 15527 = 15724
227 + 15497 = 15724
251 + 15473 = 15724
257 + 15467 = 15724

Showing the first eight; more decompositions exist.
