Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91724, here are decompositions:

13 + 91711 = 91724
103 + 91621 = 91724
151 + 91573 = 91724
211 + 91513 = 91724
271 + 91453 = 91724
313 + 91411 = 91724
331 + 91393 = 91724
337 + 91387 = 91724

Showing the first eight; more decompositions exist.
