Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83572, here are decompositions:

11 + 83561 = 83572
101 + 83471 = 83572
113 + 83459 = 83572
149 + 83423 = 83572
173 + 83399 = 83572
233 + 83339 = 83572
353 + 83219 = 83572
479 + 83093 = 83572

Showing the first eight; more decompositions exist.
