Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556286, here are decompositions:

7 + 556279 = 556286
13 + 556273 = 556286
19 + 556267 = 556286
43 + 556243 = 556286
67 + 556219 = 556286
109 + 556177 = 556286
127 + 556159 = 556286
163 + 556123 = 556286

Showing the first eight; more decompositions exist.
