Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556556, here are decompositions:

19 + 556537 = 556556
37 + 556519 = 556556
43 + 556513 = 556556
73 + 556483 = 556556
79 + 556477 = 556556
97 + 556459 = 556556
157 + 556399 = 556556
229 + 556327 = 556556

Showing the first eight; more decompositions exist.
