Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550404, here are decompositions:

53 + 550351 = 550404
67 + 550337 = 550404
137 + 550267 = 550404
163 + 550241 = 550404
191 + 550213 = 550404
193 + 550211 = 550404
223 + 550181 = 550404
227 + 550177 = 550404

Showing the first eight; more decompositions exist.
