Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556318, here are decompositions:

5 + 556313 = 556318
29 + 556289 = 556318
47 + 556271 = 556318
89 + 556229 = 556318
107 + 556211 = 556318
137 + 556181 = 556318
251 + 556067 = 556318
281 + 556037 = 556318

Showing the first eight; more decompositions exist.
