Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68218, here are decompositions:

5 + 68213 = 68218
11 + 68207 = 68218
47 + 68171 = 68218
71 + 68147 = 68218
107 + 68111 = 68218
131 + 68087 = 68218
239 + 67979 = 68218
251 + 67967 = 68218

Showing the first eight; more decompositions exist.
