Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990324, here are decompositions:

11 + 990313 = 990324
17 + 990307 = 990324
31 + 990293 = 990324
37 + 990287 = 990324
43 + 990281 = 990324
47 + 990277 = 990324
113 + 990211 = 990324
173 + 990151 = 990324

Showing the first eight; more decompositions exist.
