Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990416, here are decompositions:

19 + 990397 = 990416
67 + 990349 = 990416
103 + 990313 = 990416
109 + 990307 = 990416
127 + 990289 = 990416
139 + 990277 = 990416
157 + 990259 = 990416
373 + 990043 = 990416

Showing the first eight; more decompositions exist.
