Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556266, here are decompositions:

5 + 556261 = 556266
13 + 556253 = 556266
23 + 556243 = 556266
37 + 556229 = 556266
47 + 556219 = 556266
89 + 556177 = 556266
107 + 556159 = 556266
163 + 556103 = 556266

Showing the first eight; more decompositions exist.
