Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005230, here are decompositions:

7 + 1005223 = 1005230
13 + 1005217 = 1005230
43 + 1005187 = 1005230
97 + 1005133 = 1005230
151 + 1005079 = 1005230
157 + 1005073 = 1005230
181 + 1005049 = 1005230
211 + 1005019 = 1005230

Showing the first eight; more decompositions exist.
