Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82512, here are decompositions:

5 + 82507 = 82512
13 + 82499 = 82512
19 + 82493 = 82512
29 + 82483 = 82512
41 + 82471 = 82512
43 + 82469 = 82512
139 + 82373 = 82512
151 + 82361 = 82512

Showing the first eight; more decompositions exist.
