Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68690, here are decompositions:

3 + 68687 = 68690
7 + 68683 = 68690
31 + 68659 = 68690
79 + 68611 = 68690
109 + 68581 = 68690
151 + 68539 = 68690
199 + 68491 = 68690
241 + 68449 = 68690

Showing the first eight; more decompositions exist.
