Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556228, here are decompositions:

17 + 556211 = 556228
47 + 556181 = 556228
191 + 556037 = 556228
401 + 555827 = 556228
461 + 555767 = 556228
467 + 555761 = 556228
521 + 555707 = 556228
557 + 555671 = 556228

Showing the first eight; more decompositions exist.
