Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556994, here are decompositions:

7 + 556987 = 556994
13 + 556981 = 556994
37 + 556957 = 556994
103 + 556891 = 556994
127 + 556867 = 556994
241 + 556753 = 556994
271 + 556723 = 556994
307 + 556687 = 556994

Showing the first eight; more decompositions exist.
