Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529688, here are decompositions:

7 + 529681 = 529688
31 + 529657 = 529688
109 + 529579 = 529688
157 + 529531 = 529688
199 + 529489 = 529688
277 + 529411 = 529688
307 + 529381 = 529688
331 + 529357 = 529688

Showing the first eight; more decompositions exist.
