Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990502, here are decompositions:

5 + 990497 = 990502
113 + 990389 = 990502
131 + 990371 = 990502
173 + 990329 = 990502
179 + 990323 = 990502
263 + 990239 = 990502
449 + 990053 = 990502
479 + 990023 = 990502

Showing the first eight; more decompositions exist.
