Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556426, here are decompositions:

23 + 556403 = 556426
53 + 556373 = 556426
83 + 556343 = 556426
113 + 556313 = 556426
137 + 556289 = 556426
173 + 556253 = 556426
197 + 556229 = 556426
359 + 556067 = 556426

Showing the first eight; more decompositions exist.
