Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556222, here are decompositions:

3 + 556219 = 556222
11 + 556211 = 556222
41 + 556181 = 556222
179 + 556043 = 556222
269 + 555953 = 556222
281 + 555941 = 556222
461 + 555761 = 556222
479 + 555743 = 556222

Showing the first eight; more decompositions exist.
