Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556544, here are decompositions:

7 + 556537 = 556544
31 + 556513 = 556544
61 + 556483 = 556544
67 + 556477 = 556544
103 + 556441 = 556544
193 + 556351 = 556544
223 + 556321 = 556544
271 + 556273 = 556544

Showing the first eight; more decompositions exist.
