Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85512, here are decompositions:

43 + 85469 = 85512
59 + 85453 = 85512
61 + 85451 = 85512
73 + 85439 = 85512
83 + 85429 = 85512
101 + 85411 = 85512
131 + 85381 = 85512
149 + 85363 = 85512

Showing the first eight; more decompositions exist.
