Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67808, here are decompositions:

7 + 67801 = 67808
19 + 67789 = 67808
31 + 67777 = 67808
67 + 67741 = 67808
109 + 67699 = 67808
157 + 67651 = 67808
229 + 67579 = 67808
241 + 67567 = 67808

Showing the first eight; more decompositions exist.
