Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556466, here are decompositions:

7 + 556459 = 556466
67 + 556399 = 556466
139 + 556327 = 556466
193 + 556273 = 556466
199 + 556267 = 556466
223 + 556243 = 556466
307 + 556159 = 556466
373 + 556093 = 556466

Showing the first eight; more decompositions exist.
