Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505018, here are decompositions:

29 + 504989 = 505018
71 + 504947 = 505018
89 + 504929 = 505018
167 + 504851 = 505018
197 + 504821 = 505018
251 + 504767 = 505018
347 + 504671 = 505018
401 + 504617 = 505018

Showing the first eight; more decompositions exist.
