Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006278, here are decompositions:

11 + 1006267 = 1006278
29 + 1006249 = 1006278
37 + 1006241 = 1006278
41 + 1006237 = 1006278
47 + 1006231 = 1006278
59 + 1006219 = 1006278
61 + 1006217 = 1006278
89 + 1006189 = 1006278

Showing the first eight; more decompositions exist.
