Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990310, here are decompositions:

3 + 990307 = 990310
17 + 990293 = 990310
23 + 990287 = 990310
29 + 990281 = 990310
71 + 990239 = 990310
131 + 990179 = 990310
173 + 990137 = 990310
257 + 990053 = 990310

Showing the first eight; more decompositions exist.
