Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82542, here are decompositions:

11 + 82531 = 82542
13 + 82529 = 82542
43 + 82499 = 82542
59 + 82483 = 82542
71 + 82471 = 82542
73 + 82469 = 82542
79 + 82463 = 82542
149 + 82393 = 82542

Showing the first eight; more decompositions exist.
