Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83712, here are decompositions:

11 + 83701 = 83712
23 + 83689 = 83712
59 + 83653 = 83712
71 + 83641 = 83712
73 + 83639 = 83712
103 + 83609 = 83712
149 + 83563 = 83712
151 + 83561 = 83712

Showing the first eight; more decompositions exist.
