Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523458, here are decompositions:

31 + 523427 = 523458
41 + 523417 = 523458
71 + 523387 = 523458
101 + 523357 = 523458
107 + 523351 = 523458
109 + 523349 = 523458
151 + 523307 = 523458
197 + 523261 = 523458

Showing the first eight; more decompositions exist.
