Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505478, here are decompositions:

19 + 505459 = 505478
31 + 505447 = 505478
67 + 505411 = 505478
79 + 505399 = 505478
109 + 505369 = 505478
139 + 505339 = 505478
151 + 505327 = 505478
157 + 505321 = 505478

Showing the first eight; more decompositions exist.
