Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82562, here are decompositions:

3 + 82559 = 82562
13 + 82549 = 82562
31 + 82531 = 82562
79 + 82483 = 82562
211 + 82351 = 82562
223 + 82339 = 82562
283 + 82279 = 82562
331 + 82231 = 82562

Showing the first eight; more decompositions exist.
