Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005228, here are decompositions:

5 + 1005223 = 1005228
11 + 1005217 = 1005228
19 + 1005209 = 1005228
41 + 1005187 = 1005228
67 + 1005161 = 1005228
97 + 1005131 = 1005228
127 + 1005101 = 1005228
149 + 1005079 = 1005228

Showing the first eight; more decompositions exist.
