Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556550, here are decompositions:

13 + 556537 = 556550
31 + 556519 = 556550
37 + 556513 = 556550
67 + 556483 = 556550
73 + 556477 = 556550
109 + 556441 = 556550
151 + 556399 = 556550
199 + 556351 = 556550

Showing the first eight; more decompositions exist.
