Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505558, here are decompositions:

47 + 505511 = 505558
89 + 505469 = 505558
149 + 505409 = 505558
191 + 505367 = 505558
239 + 505319 = 505558
257 + 505301 = 505558
281 + 505277 = 505558
401 + 505157 = 505558

Showing the first eight; more decompositions exist.
