Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505426, here are decompositions:

17 + 505409 = 505426
59 + 505367 = 505426
107 + 505319 = 505426
113 + 505313 = 505426
149 + 505277 = 505426
239 + 505187 = 505426
269 + 505157 = 505426
353 + 505073 = 505426

Showing the first eight; more decompositions exist.
