Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556356, here are decompositions:

5 + 556351 = 556356
13 + 556343 = 556356
29 + 556327 = 556356
43 + 556313 = 556356
67 + 556289 = 556356
83 + 556273 = 556356
89 + 556267 = 556356
103 + 556253 = 556356

Showing the first eight; more decompositions exist.
