Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556988, here are decompositions:

7 + 556981 = 556988
31 + 556957 = 556988
97 + 556891 = 556988
127 + 556861 = 556988
139 + 556849 = 556988
199 + 556789 = 556988
337 + 556651 = 556988
349 + 556639 = 556988

Showing the first eight; more decompositions exist.
