Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005408, here are decompositions:

17 + 1005391 = 1005408
37 + 1005371 = 1005408
59 + 1005349 = 1005408
139 + 1005269 = 1005408
167 + 1005241 = 1005408
179 + 1005229 = 1005408
191 + 1005217 = 1005408
199 + 1005209 = 1005408

Showing the first eight; more decompositions exist.
