Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990504, here are decompositions:

7 + 990497 = 990504
17 + 990487 = 990504
41 + 990463 = 990504
107 + 990397 = 990504
127 + 990377 = 990504
173 + 990331 = 990504
181 + 990323 = 990504
191 + 990313 = 990504

Showing the first eight; more decompositions exist.
