Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82612, here are decompositions:

3 + 82609 = 82612
11 + 82601 = 82612
41 + 82571 = 82612
53 + 82559 = 82612
83 + 82529 = 82612
113 + 82499 = 82612
149 + 82463 = 82612
191 + 82421 = 82612

Showing the first eight; more decompositions exist.
