Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556256, here are decompositions:

3 + 556253 = 556256
13 + 556243 = 556256
37 + 556219 = 556256
79 + 556177 = 556256
97 + 556159 = 556256
163 + 556093 = 556256
229 + 556027 = 556256
433 + 555823 = 556256

Showing the first eight; more decompositions exist.
