Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68140, here are decompositions:

29 + 68111 = 68140
41 + 68099 = 68140
53 + 68087 = 68140
173 + 67967 = 68140
179 + 67961 = 68140
197 + 67943 = 68140
239 + 67901 = 68140
257 + 67883 = 68140

Showing the first eight; more decompositions exist.
