Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505436, here are decompositions:

7 + 505429 = 505436
37 + 505399 = 505436
67 + 505369 = 505436
79 + 505357 = 505436
97 + 505339 = 505436
109 + 505327 = 505436
157 + 505279 = 505436
199 + 505237 = 505436

Showing the first eight; more decompositions exist.
