Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68840, here are decompositions:

19 + 68821 = 68840
73 + 68767 = 68840
97 + 68743 = 68840
103 + 68737 = 68840
127 + 68713 = 68840
157 + 68683 = 68840
181 + 68659 = 68840
229 + 68611 = 68840

Showing the first eight; more decompositions exist.
