Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82420, here are decompositions:

47 + 82373 = 82420
59 + 82361 = 82420
71 + 82349 = 82420
113 + 82307 = 82420
179 + 82241 = 82420
197 + 82223 = 82420
227 + 82193 = 82420
257 + 82163 = 82420

Showing the first eight; more decompositions exist.
