Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82266, here are decompositions:

5 + 82261 = 82266
29 + 82237 = 82266
43 + 82223 = 82266
47 + 82219 = 82266
59 + 82207 = 82266
73 + 82193 = 82266
83 + 82183 = 82266
103 + 82163 = 82266

Showing the first eight; more decompositions exist.
