Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008280, here are decompositions:

17 + 1008263 = 1008280
23 + 1008257 = 1008280
41 + 1008239 = 1008280
47 + 1008233 = 1008280
71 + 1008209 = 1008280
149 + 1008131 = 1008280
179 + 1008101 = 1008280
239 + 1008041 = 1008280

Showing the first eight; more decompositions exist.
