Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990068, here are decompositions:

31 + 990037 = 990068
67 + 990001 = 990068
97 + 989971 = 990068
109 + 989959 = 990068
139 + 989929 = 990068
151 + 989917 = 990068
181 + 989887 = 990068
199 + 989869 = 990068

Showing the first eight; more decompositions exist.
