Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68688, here are decompositions:

5 + 68683 = 68688
19 + 68669 = 68688
29 + 68659 = 68688
107 + 68581 = 68688
149 + 68539 = 68688
157 + 68531 = 68688
167 + 68521 = 68688
181 + 68507 = 68688

Showing the first eight; more decompositions exist.
