Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990126, here are decompositions:

73 + 990053 = 990126
83 + 990043 = 990126
89 + 990037 = 990126
103 + 990023 = 990126
113 + 990013 = 990126
127 + 989999 = 990126
149 + 989977 = 990126
167 + 989959 = 990126

Showing the first eight; more decompositions exist.
