Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005256, here are decompositions:

17 + 1005239 = 1005256
47 + 1005209 = 1005256
53 + 1005203 = 1005256
113 + 1005143 = 1005256
149 + 1005107 = 1005256
227 + 1005029 = 1005256
269 + 1004987 = 1005256
293 + 1004963 = 1005256

Showing the first eight; more decompositions exist.
