Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990618, here are decompositions:

19 + 990599 = 990618
29 + 990589 = 990618
59 + 990559 = 990618
71 + 990547 = 990618
89 + 990529 = 990618
107 + 990511 = 990618
131 + 990487 = 990618
149 + 990469 = 990618

Showing the first eight; more decompositions exist.
