Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556558, here are decompositions:

71 + 556487 = 556558
227 + 556331 = 556558
269 + 556289 = 556558
347 + 556211 = 556558
491 + 556067 = 556558
521 + 556037 = 556558
617 + 555941 = 556558
701 + 555857 = 556558

Showing the first eight; more decompositions exist.
