Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529666, here are decompositions:

17 + 529649 = 529666
29 + 529637 = 529666
47 + 529619 = 529666
89 + 529577 = 529666
149 + 529517 = 529666
317 + 529349 = 529666
353 + 529313 = 529666
359 + 529307 = 529666

Showing the first eight; more decompositions exist.
