Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68404, here are decompositions:

5 + 68399 = 68404
53 + 68351 = 68404
191 + 68213 = 68404
197 + 68207 = 68404
233 + 68171 = 68404
257 + 68147 = 68404
263 + 68141 = 68404
293 + 68111 = 68404

Showing the first eight; more decompositions exist.
