Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68906, here are decompositions:

3 + 68903 = 68906
7 + 68899 = 68906
43 + 68863 = 68906
139 + 68767 = 68906
157 + 68749 = 68906
163 + 68743 = 68906
193 + 68713 = 68906
223 + 68683 = 68906

Showing the first eight; more decompositions exist.
