Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556428, here are decompositions:

29 + 556399 = 556428
97 + 556331 = 556428
101 + 556327 = 556428
107 + 556321 = 556428
139 + 556289 = 556428
149 + 556279 = 556428
157 + 556271 = 556428
167 + 556261 = 556428

Showing the first eight; more decompositions exist.
