Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556664, here are decompositions:

13 + 556651 = 556664
37 + 556627 = 556664
127 + 556537 = 556664
151 + 556513 = 556664
181 + 556483 = 556664
223 + 556441 = 556664
313 + 556351 = 556664
337 + 556327 = 556664

Showing the first eight; more decompositions exist.
