Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82280, here are decompositions:

13 + 82267 = 82280
19 + 82261 = 82280
43 + 82237 = 82280
61 + 82219 = 82280
73 + 82207 = 82280
97 + 82183 = 82280
109 + 82171 = 82280
127 + 82153 = 82280

Showing the first eight; more decompositions exist.
