Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005494, here are decompositions:

13 + 1005481 = 1005494
37 + 1005457 = 1005494
67 + 1005427 = 1005494
103 + 1005391 = 1005494
163 + 1005331 = 1005494
181 + 1005313 = 1005494
271 + 1005223 = 1005494
277 + 1005217 = 1005494

Showing the first eight; more decompositions exist.
