Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505356, here are decompositions:

17 + 505339 = 505356
29 + 505327 = 505356
37 + 505319 = 505356
43 + 505313 = 505356
73 + 505283 = 505356
79 + 505277 = 505356
197 + 505159 = 505356
199 + 505157 = 505356

Showing the first eight; more decompositions exist.
