Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990662, here are decompositions:

19 + 990643 = 990662
31 + 990631 = 990662
73 + 990589 = 990662
103 + 990559 = 990662
139 + 990523 = 990662
151 + 990511 = 990662
193 + 990469 = 990662
199 + 990463 = 990662

Showing the first eight; more decompositions exist.
