Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556494, here are decompositions:

7 + 556487 = 556494
11 + 556483 = 556494
17 + 556477 = 556494
53 + 556441 = 556494
151 + 556343 = 556494
163 + 556331 = 556494
167 + 556327 = 556494
173 + 556321 = 556494

Showing the first eight; more decompositions exist.
