Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990162, here are decompositions:

11 + 990151 = 990162
109 + 990053 = 990162
139 + 990023 = 990162
149 + 990013 = 990162
163 + 989999 = 990162
181 + 989981 = 990162
191 + 989971 = 990162
211 + 989951 = 990162

Showing the first eight; more decompositions exist.
