Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556536, here are decompositions:

17 + 556519 = 556536
23 + 556513 = 556536
53 + 556483 = 556536
59 + 556477 = 556536
137 + 556399 = 556536
163 + 556373 = 556536
193 + 556343 = 556536
223 + 556313 = 556536

Showing the first eight; more decompositions exist.
