Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85572, here are decompositions:

23 + 85549 = 85572
41 + 85531 = 85572
59 + 85513 = 85572
103 + 85469 = 85572
191 + 85381 = 85572
211 + 85361 = 85572
239 + 85333 = 85572
241 + 85331 = 85572

Showing the first eight; more decompositions exist.
