Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505494, here are decompositions:

13 + 505481 = 505494
47 + 505447 = 505494
83 + 505411 = 505494
127 + 505367 = 505494
137 + 505357 = 505494
167 + 505327 = 505494
173 + 505321 = 505494
181 + 505313 = 505494

Showing the first eight; more decompositions exist.
