Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556898, here are decompositions:

7 + 556891 = 556898
31 + 556867 = 556898
37 + 556861 = 556898
79 + 556819 = 556898
109 + 556789 = 556898
157 + 556741 = 556898
211 + 556687 = 556898
271 + 556627 = 556898

Showing the first eight; more decompositions exist.
