Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990612, here are decompositions:

13 + 990599 = 990612
19 + 990593 = 990612
23 + 990589 = 990612
53 + 990559 = 990612
83 + 990529 = 990612
89 + 990523 = 990612
101 + 990511 = 990612
109 + 990503 = 990612

Showing the first eight; more decompositions exist.
