Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71656, here are decompositions:

23 + 71633 = 71656
59 + 71597 = 71656
107 + 71549 = 71656
173 + 71483 = 71656
227 + 71429 = 71656
257 + 71399 = 71656
269 + 71387 = 71656
293 + 71363 = 71656

Showing the first eight; more decompositions exist.
