Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505424, here are decompositions:

13 + 505411 = 505424
67 + 505357 = 505424
97 + 505327 = 505424
103 + 505321 = 505424
193 + 505231 = 505424
211 + 505213 = 505424
223 + 505201 = 505424
307 + 505117 = 505424

Showing the first eight; more decompositions exist.
