Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68638, here are decompositions:

5 + 68633 = 68638
41 + 68597 = 68638
71 + 68567 = 68638
107 + 68531 = 68638
131 + 68507 = 68638
137 + 68501 = 68638
149 + 68489 = 68638
191 + 68447 = 68638

Showing the first eight; more decompositions exist.
