Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990168, here are decompositions:

5 + 990163 = 990168
17 + 990151 = 990168
31 + 990137 = 990168
131 + 990037 = 990168
167 + 990001 = 990168
191 + 989977 = 990168
197 + 989971 = 990168
229 + 989939 = 990168

Showing the first eight; more decompositions exist.
