Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85688, here are decompositions:

19 + 85669 = 85688
61 + 85627 = 85688
67 + 85621 = 85688
139 + 85549 = 85688
157 + 85531 = 85688
241 + 85447 = 85688
277 + 85411 = 85688
307 + 85381 = 85688

Showing the first eight; more decompositions exist.
