Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005288, here are decompositions:

19 + 1005269 = 1005288
47 + 1005241 = 1005288
59 + 1005229 = 1005288
71 + 1005217 = 1005288
79 + 1005209 = 1005288
101 + 1005187 = 1005288
127 + 1005161 = 1005288
157 + 1005131 = 1005288

Showing the first eight; more decompositions exist.
