Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556562, here are decompositions:

3 + 556559 = 556562
43 + 556519 = 556562
79 + 556483 = 556562
103 + 556459 = 556562
163 + 556399 = 556562
211 + 556351 = 556562
241 + 556321 = 556562
283 + 556279 = 556562

Showing the first eight; more decompositions exist.
