Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990156, here are decompositions:

5 + 990151 = 990156
19 + 990137 = 990156
103 + 990053 = 990156
113 + 990043 = 990156
157 + 989999 = 990156
179 + 989977 = 990156
197 + 989959 = 990156
227 + 989929 = 990156

Showing the first eight; more decompositions exist.
