Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556322, here are decompositions:

43 + 556279 = 556322
61 + 556261 = 556322
79 + 556243 = 556322
103 + 556219 = 556322
163 + 556159 = 556322
199 + 556123 = 556322
229 + 556093 = 556322
271 + 556051 = 556322

Showing the first eight; more decompositions exist.
