Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82556, here are decompositions:

7 + 82549 = 82556
73 + 82483 = 82556
163 + 82393 = 82556
277 + 82279 = 82556
337 + 82219 = 82556
349 + 82207 = 82556
367 + 82189 = 82556
373 + 82183 = 82556

Showing the first eight; more decompositions exist.
