Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556420, here are decompositions:

17 + 556403 = 556420
47 + 556373 = 556420
89 + 556331 = 556420
107 + 556313 = 556420
131 + 556289 = 556420
149 + 556271 = 556420
167 + 556253 = 556420
191 + 556229 = 556420

Showing the first eight; more decompositions exist.
