Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006280, here are decompositions:

13 + 1006267 = 1006280
31 + 1006249 = 1006280
43 + 1006237 = 1006280
61 + 1006219 = 1006280
103 + 1006177 = 1006280
109 + 1006171 = 1006280
127 + 1006153 = 1006280
157 + 1006123 = 1006280

Showing the first eight; more decompositions exist.
