Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505432, here are decompositions:

3 + 505429 = 505432
23 + 505409 = 505432
113 + 505319 = 505432
131 + 505301 = 505432
149 + 505283 = 505432
251 + 505181 = 505432
293 + 505139 = 505432
359 + 505073 = 505432

Showing the first eight; more decompositions exist.
