Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82786, here are decompositions:

5 + 82781 = 82786
23 + 82763 = 82786
29 + 82757 = 82786
59 + 82727 = 82786
167 + 82619 = 82786
173 + 82613 = 82786
227 + 82559 = 82786
257 + 82529 = 82786

Showing the first eight; more decompositions exist.
