Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85726, here are decompositions:

23 + 85703 = 85726
59 + 85667 = 85726
83 + 85643 = 85726
107 + 85619 = 85726
149 + 85577 = 85726
239 + 85487 = 85726
257 + 85469 = 85726
467 + 85259 = 85726

Showing the first eight; more decompositions exist.
