Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005268, here are decompositions:

29 + 1005239 = 1005268
59 + 1005209 = 1005268
107 + 1005161 = 1005268
137 + 1005131 = 1005268
167 + 1005101 = 1005268
197 + 1005071 = 1005268
227 + 1005041 = 1005268
239 + 1005029 = 1005268

Showing the first eight; more decompositions exist.
