Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556224, here are decompositions:

5 + 556219 = 556224
13 + 556211 = 556224
43 + 556181 = 556224
47 + 556177 = 556224
101 + 556123 = 556224
131 + 556093 = 556224
157 + 556067 = 556224
173 + 556051 = 556224

Showing the first eight; more decompositions exist.
