Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990524, here are decompositions:

13 + 990511 = 990524
37 + 990487 = 990524
61 + 990463 = 990524
127 + 990397 = 990524
163 + 990361 = 990524
193 + 990331 = 990524
211 + 990313 = 990524
313 + 990211 = 990524

Showing the first eight; more decompositions exist.
