Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005306, here are decompositions:

13 + 1005293 = 1005306
19 + 1005287 = 1005306
37 + 1005269 = 1005306
67 + 1005239 = 1005306
83 + 1005223 = 1005306
89 + 1005217 = 1005306
97 + 1005209 = 1005306
103 + 1005203 = 1005306

Showing the first eight; more decompositions exist.
