Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505404, here are decompositions:

5 + 505399 = 505404
37 + 505367 = 505404
47 + 505357 = 505404
83 + 505321 = 505404
103 + 505301 = 505404
127 + 505277 = 505404
167 + 505237 = 505404
173 + 505231 = 505404

Showing the first eight; more decompositions exist.
