Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556582, here are decompositions:

3 + 556579 = 556582
23 + 556559 = 556582
179 + 556403 = 556582
239 + 556343 = 556582
251 + 556331 = 556582
269 + 556313 = 556582
293 + 556289 = 556582
311 + 556271 = 556582

Showing the first eight; more decompositions exist.
