Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556828, here are decompositions:

5 + 556823 = 556828
11 + 556817 = 556828
17 + 556811 = 556828
29 + 556799 = 556828
47 + 556781 = 556828
59 + 556769 = 556828
101 + 556727 = 556828
131 + 556697 = 556828

Showing the first eight; more decompositions exist.
