Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990512, here are decompositions:

43 + 990469 = 990512
151 + 990361 = 990512
163 + 990349 = 990512
181 + 990331 = 990512
199 + 990313 = 990512
223 + 990289 = 990512
331 + 990181 = 990512
349 + 990163 = 990512

Showing the first eight; more decompositions exist.
