Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556636, here are decompositions:

23 + 556613 = 556636
29 + 556607 = 556636
53 + 556583 = 556636
149 + 556487 = 556636
233 + 556403 = 556636
263 + 556373 = 556636
293 + 556343 = 556636
347 + 556289 = 556636

Showing the first eight; more decompositions exist.
