Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990136, here are decompositions:

83 + 990053 = 990136
113 + 990023 = 990136
137 + 989999 = 990136
197 + 989939 = 990136
227 + 989909 = 990136
263 + 989873 = 990136
353 + 989783 = 990136
359 + 989777 = 990136

Showing the first eight; more decompositions exist.
