Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71712, here are decompositions:

5 + 71707 = 71712
13 + 71699 = 71712
19 + 71693 = 71712
41 + 71671 = 71712
79 + 71633 = 71712
149 + 71563 = 71712
163 + 71549 = 71712
229 + 71483 = 71712

Showing the first eight; more decompositions exist.
