Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990508, here are decompositions:

5 + 990503 = 990508
11 + 990497 = 990508
131 + 990377 = 990508
137 + 990371 = 990508
149 + 990359 = 990508
179 + 990329 = 990508
227 + 990281 = 990508
269 + 990239 = 990508

Showing the first eight; more decompositions exist.
