Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43726, here are decompositions:

5 + 43721 = 43726
113 + 43613 = 43726
149 + 43577 = 43726
227 + 43499 = 43726
239 + 43487 = 43726
269 + 43457 = 43726
443 + 43283 = 43726
503 + 43223 = 43726

Showing the first eight; more decompositions exist.
