Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556406, here are decompositions:

3 + 556403 = 556406
7 + 556399 = 556406
79 + 556327 = 556406
127 + 556279 = 556406
139 + 556267 = 556406
163 + 556243 = 556406
229 + 556177 = 556406
283 + 556123 = 556406

Showing the first eight; more decompositions exist.
