Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85566, here are decompositions:

17 + 85549 = 85566
43 + 85523 = 85566
53 + 85513 = 85566
79 + 85487 = 85566
97 + 85469 = 85566
113 + 85453 = 85566
127 + 85439 = 85566
137 + 85429 = 85566

Showing the first eight; more decompositions exist.
