Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556284, here are decompositions:

5 + 556279 = 556284
11 + 556273 = 556284
13 + 556271 = 556284
17 + 556267 = 556284
23 + 556261 = 556284
31 + 556253 = 556284
41 + 556243 = 556284
73 + 556211 = 556284

Showing the first eight; more decompositions exist.
