Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990344, here are decompositions:

13 + 990331 = 990344
31 + 990313 = 990344
37 + 990307 = 990344
67 + 990277 = 990344
163 + 990181 = 990344
181 + 990163 = 990344
193 + 990151 = 990344
307 + 990037 = 990344

Showing the first eight; more decompositions exist.
