Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556444, here are decompositions:

3 + 556441 = 556444
41 + 556403 = 556444
71 + 556373 = 556444
101 + 556343 = 556444
113 + 556331 = 556444
131 + 556313 = 556444
173 + 556271 = 556444
191 + 556253 = 556444

Showing the first eight; more decompositions exist.
