Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68278, here are decompositions:

17 + 68261 = 68278
59 + 68219 = 68278
71 + 68207 = 68278
107 + 68171 = 68278
131 + 68147 = 68278
137 + 68141 = 68278
167 + 68111 = 68278
179 + 68099 = 68278

Showing the first eight; more decompositions exist.
