Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556522, here are decompositions:

3 + 556519 = 556522
149 + 556373 = 556522
179 + 556343 = 556522
191 + 556331 = 556522
233 + 556289 = 556522
251 + 556271 = 556522
269 + 556253 = 556522
293 + 556229 = 556522

Showing the first eight; more decompositions exist.
