Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555478, here are decompositions:

17 + 555461 = 555478
59 + 555419 = 555478
191 + 555287 = 555478
227 + 555251 = 555478
257 + 555221 = 555478
269 + 555209 = 555478
311 + 555167 = 555478
359 + 555119 = 555478

Showing the first eight; more decompositions exist.
