Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990330, here are decompositions:

7 + 990323 = 990330
17 + 990313 = 990330
23 + 990307 = 990330
37 + 990293 = 990330
41 + 990289 = 990330
43 + 990287 = 990330
53 + 990277 = 990330
71 + 990259 = 990330

Showing the first eight; more decompositions exist.
