Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990312, here are decompositions:

5 + 990307 = 990312
19 + 990293 = 990312
23 + 990289 = 990312
31 + 990281 = 990312
53 + 990259 = 990312
73 + 990239 = 990312
101 + 990211 = 990312
131 + 990181 = 990312

Showing the first eight; more decompositions exist.
