Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990386, here are decompositions:

3 + 990383 = 990386
37 + 990349 = 990386
73 + 990313 = 990386
79 + 990307 = 990386
97 + 990289 = 990386
109 + 990277 = 990386
127 + 990259 = 990386
223 + 990163 = 990386

Showing the first eight; more decompositions exist.
