Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71638, here are decompositions:

5 + 71633 = 71638
41 + 71597 = 71638
89 + 71549 = 71638
101 + 71537 = 71638
167 + 71471 = 71638
227 + 71411 = 71638
239 + 71399 = 71638
251 + 71387 = 71638

Showing the first eight; more decompositions exist.
