Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005538, here are decompositions:

11 + 1005527 = 1005538
71 + 1005467 = 1005538
101 + 1005437 = 1005538
167 + 1005371 = 1005538
179 + 1005359 = 1005538
251 + 1005287 = 1005538
269 + 1005269 = 1005538
431 + 1005107 = 1005538

Showing the first eight; more decompositions exist.
