Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526666, here are decompositions:

17 + 526649 = 526666
29 + 526637 = 526666
47 + 526619 = 526666
83 + 526583 = 526666
167 + 526499 = 526666
269 + 526397 = 526666
293 + 526373 = 526666
359 + 526307 = 526666

Showing the first eight; more decompositions exist.
