Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82458, here are decompositions:

37 + 82421 = 82458
71 + 82387 = 82458
97 + 82361 = 82458
107 + 82351 = 82458
109 + 82349 = 82458
151 + 82307 = 82458
157 + 82301 = 82458
179 + 82279 = 82458

Showing the first eight; more decompositions exist.
