Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990482, here are decompositions:

13 + 990469 = 990482
19 + 990463 = 990482
151 + 990331 = 990482
193 + 990289 = 990482
223 + 990259 = 990482
271 + 990211 = 990482
313 + 990169 = 990482
331 + 990151 = 990482

Showing the first eight; more decompositions exist.
