Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990392, here are decompositions:

3 + 990389 = 990392
31 + 990361 = 990392
43 + 990349 = 990392
61 + 990331 = 990392
79 + 990313 = 990392
103 + 990289 = 990392
181 + 990211 = 990392
211 + 990181 = 990392

Showing the first eight; more decompositions exist.
