Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990116, here are decompositions:

73 + 990043 = 990116
79 + 990037 = 990116
103 + 990013 = 990116
139 + 989977 = 990116
157 + 989959 = 990116
199 + 989917 = 990116
229 + 989887 = 990116
277 + 989839 = 990116

Showing the first eight; more decompositions exist.
