Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82682, here are decompositions:

31 + 82651 = 82682
73 + 82609 = 82682
151 + 82531 = 82682
199 + 82483 = 82682
211 + 82471 = 82682
331 + 82351 = 82682
421 + 82261 = 82682
463 + 82219 = 82682

Showing the first eight; more decompositions exist.
