Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990320, here are decompositions:

7 + 990313 = 990320
13 + 990307 = 990320
31 + 990289 = 990320
43 + 990277 = 990320
61 + 990259 = 990320
109 + 990211 = 990320
139 + 990181 = 990320
151 + 990169 = 990320

Showing the first eight; more decompositions exist.
