Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005356, here are decompositions:

7 + 1005349 = 1005356
43 + 1005313 = 1005356
127 + 1005229 = 1005356
139 + 1005217 = 1005356
223 + 1005133 = 1005356
277 + 1005079 = 1005356
283 + 1005073 = 1005356
307 + 1005049 = 1005356

Showing the first eight; more decompositions exist.
