Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990998, here are decompositions:

31 + 990967 = 990998
37 + 990961 = 990998
109 + 990889 = 990998
157 + 990841 = 990998
199 + 990799 = 990998
367 + 990631 = 990998
409 + 990589 = 990998
439 + 990559 = 990998

Showing the first eight; more decompositions exist.
