Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505418, here are decompositions:

7 + 505411 = 505418
19 + 505399 = 505418
61 + 505357 = 505418
79 + 505339 = 505418
97 + 505321 = 505418
139 + 505279 = 505418
181 + 505237 = 505418
307 + 505111 = 505418

Showing the first eight; more decompositions exist.
