Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82566, here are decompositions:

5 + 82561 = 82566
7 + 82559 = 82566
17 + 82549 = 82566
37 + 82529 = 82566
59 + 82507 = 82566
67 + 82499 = 82566
73 + 82493 = 82566
79 + 82487 = 82566

Showing the first eight; more decompositions exist.
