Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005526, here are decompositions:

23 + 1005503 = 1005526
59 + 1005467 = 1005526
89 + 1005437 = 1005526
113 + 1005413 = 1005526
167 + 1005359 = 1005526
233 + 1005293 = 1005526
239 + 1005287 = 1005526
257 + 1005269 = 1005526

Showing the first eight; more decompositions exist.
