Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82530, here are decompositions:

23 + 82507 = 82530
31 + 82499 = 82530
37 + 82493 = 82530
43 + 82487 = 82530
47 + 82483 = 82530
59 + 82471 = 82530
61 + 82469 = 82530
67 + 82463 = 82530

Showing the first eight; more decompositions exist.
