Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85676, here are decompositions:

7 + 85669 = 85676
37 + 85639 = 85676
79 + 85597 = 85676
127 + 85549 = 85676
163 + 85513 = 85676
223 + 85453 = 85676
229 + 85447 = 85676
307 + 85369 = 85676

Showing the first eight; more decompositions exist.
