Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82572, here are decompositions:

5 + 82567 = 82572
11 + 82561 = 82572
13 + 82559 = 82572
23 + 82549 = 82572
41 + 82531 = 82572
43 + 82529 = 82572
73 + 82499 = 82572
79 + 82493 = 82572

Showing the first eight; more decompositions exist.
