Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85636, here are decompositions:

17 + 85619 = 85636
29 + 85607 = 85636
59 + 85577 = 85636
113 + 85523 = 85636
149 + 85487 = 85636
167 + 85469 = 85636
197 + 85439 = 85636
389 + 85247 = 85636

Showing the first eight; more decompositions exist.
