Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556378, here are decompositions:

5 + 556373 = 556378
47 + 556331 = 556378
89 + 556289 = 556378
107 + 556271 = 556378
149 + 556229 = 556378
167 + 556211 = 556378
197 + 556181 = 556378
311 + 556067 = 556378

Showing the first eight; more decompositions exist.
