Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556438, here are decompositions:

107 + 556331 = 556438
149 + 556289 = 556438
167 + 556271 = 556438
227 + 556211 = 556438
257 + 556181 = 556438
401 + 556037 = 556438
431 + 556007 = 556438
677 + 555761 = 556438

Showing the first eight; more decompositions exist.
