Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990554, here are decompositions:

7 + 990547 = 990554
31 + 990523 = 990554
43 + 990511 = 990554
67 + 990487 = 990554
157 + 990397 = 990554
193 + 990361 = 990554
223 + 990331 = 990554
241 + 990313 = 990554

Showing the first eight; more decompositions exist.
