Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556290, here are decompositions:

11 + 556279 = 556290
17 + 556273 = 556290
19 + 556271 = 556290
23 + 556267 = 556290
29 + 556261 = 556290
37 + 556253 = 556290
47 + 556243 = 556290
61 + 556229 = 556290

Showing the first eight; more decompositions exist.
