Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005668, here are decompositions:

7 + 1005661 = 1005668
31 + 1005637 = 1005668
127 + 1005541 = 1005668
211 + 1005457 = 1005668
229 + 1005439 = 1005668
241 + 1005427 = 1005668
277 + 1005391 = 1005668
337 + 1005331 = 1005668

Showing the first eight; more decompositions exist.
