Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556528, here are decompositions:

41 + 556487 = 556528
197 + 556331 = 556528
239 + 556289 = 556528
257 + 556271 = 556528
317 + 556211 = 556528
347 + 556181 = 556528
461 + 556067 = 556528
491 + 556037 = 556528

Showing the first eight; more decompositions exist.
