Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990590, here are decompositions:

31 + 990559 = 990590
43 + 990547 = 990590
61 + 990529 = 990590
67 + 990523 = 990590
79 + 990511 = 990590
103 + 990487 = 990590
127 + 990463 = 990590
193 + 990397 = 990590

Showing the first eight; more decompositions exist.
