Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556326, here are decompositions:

5 + 556321 = 556326
13 + 556313 = 556326
37 + 556289 = 556326
47 + 556279 = 556326
53 + 556273 = 556326
59 + 556267 = 556326
73 + 556253 = 556326
83 + 556243 = 556326

Showing the first eight; more decompositions exist.
