Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556998, here are decompositions:

11 + 556987 = 556998
17 + 556981 = 556998
31 + 556967 = 556998
41 + 556957 = 556998
59 + 556939 = 556998
67 + 556931 = 556998
107 + 556891 = 556998
131 + 556867 = 556998

Showing the first eight; more decompositions exist.
