Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556888, here are decompositions:

5 + 556883 = 556888
29 + 556859 = 556888
47 + 556841 = 556888
71 + 556817 = 556888
89 + 556799 = 556888
107 + 556781 = 556888
179 + 556709 = 556888
191 + 556697 = 556888

Showing the first eight; more decompositions exist.
