Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005270, here are decompositions:

29 + 1005241 = 1005270
31 + 1005239 = 1005270
41 + 1005229 = 1005270
47 + 1005223 = 1005270
53 + 1005217 = 1005270
61 + 1005209 = 1005270
67 + 1005203 = 1005270
83 + 1005187 = 1005270

Showing the first eight; more decompositions exist.
