Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529668, here are decompositions:

11 + 529657 = 529668
19 + 529649 = 529668
31 + 529637 = 529668
89 + 529579 = 529668
137 + 529531 = 529668
149 + 529519 = 529668
151 + 529517 = 529668
179 + 529489 = 529668

Showing the first eight; more decompositions exist.
