Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68540, here are decompositions:

19 + 68521 = 68540
67 + 68473 = 68540
97 + 68443 = 68540
103 + 68437 = 68540
151 + 68389 = 68540
211 + 68329 = 68540
229 + 68311 = 68540
313 + 68227 = 68540

Showing the first eight; more decompositions exist.
