Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505570, here are decompositions:

11 + 505559 = 505570
47 + 505523 = 505570
59 + 505511 = 505570
89 + 505481 = 505570
101 + 505469 = 505570
251 + 505319 = 505570
257 + 505313 = 505570
269 + 505301 = 505570

Showing the first eight; more decompositions exist.
