Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68930, here are decompositions:

3 + 68927 = 68930
13 + 68917 = 68930
31 + 68899 = 68930
67 + 68863 = 68930
109 + 68821 = 68930
139 + 68791 = 68930
163 + 68767 = 68930
181 + 68749 = 68930

Showing the first eight; more decompositions exist.
