Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990950, here are decompositions:

61 + 990889 = 990950
109 + 990841 = 990950
151 + 990799 = 990950
277 + 990673 = 990950
307 + 990643 = 990950
313 + 990637 = 990950
421 + 990529 = 990950
439 + 990511 = 990950

Showing the first eight; more decompositions exist.
