Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990588, here are decompositions:

29 + 990559 = 990588
41 + 990547 = 990588
59 + 990529 = 990588
101 + 990487 = 990588
191 + 990397 = 990588
199 + 990389 = 990588
211 + 990377 = 990588
227 + 990361 = 990588

Showing the first eight; more decompositions exist.
