Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529638, here are decompositions:

19 + 529619 = 529638
59 + 529579 = 529638
61 + 529577 = 529638
107 + 529531 = 529638
149 + 529489 = 529638
167 + 529471 = 529638
227 + 529411 = 529638
257 + 529381 = 529638

Showing the first eight; more decompositions exist.
