Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990234, here are decompositions:

23 + 990211 = 990234
53 + 990181 = 990234
71 + 990163 = 990234
83 + 990151 = 990234
97 + 990137 = 990234
181 + 990053 = 990234
191 + 990043 = 990234
197 + 990037 = 990234

Showing the first eight; more decompositions exist.
