Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556450, here are decompositions:

47 + 556403 = 556450
107 + 556343 = 556450
137 + 556313 = 556450
179 + 556271 = 556450
197 + 556253 = 556450
239 + 556211 = 556450
269 + 556181 = 556450
347 + 556103 = 556450

Showing the first eight; more decompositions exist.
