Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990326, here are decompositions:

3 + 990323 = 990326
13 + 990313 = 990326
19 + 990307 = 990326
37 + 990289 = 990326
67 + 990259 = 990326
157 + 990169 = 990326
163 + 990163 = 990326
283 + 990043 = 990326

Showing the first eight; more decompositions exist.
