Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005320, here are decompositions:

3 + 1005317 = 1005320
7 + 1005313 = 1005320
79 + 1005241 = 1005320
97 + 1005223 = 1005320
103 + 1005217 = 1005320
241 + 1005079 = 1005320
271 + 1005049 = 1005320
307 + 1005013 = 1005320

Showing the first eight; more decompositions exist.
