Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87712, here are decompositions:

11 + 87701 = 87712
29 + 87683 = 87712
41 + 87671 = 87712
71 + 87641 = 87712
83 + 87629 = 87712
89 + 87623 = 87712
173 + 87539 = 87712
239 + 87473 = 87712

Showing the first eight; more decompositions exist.
