Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529768, here are decompositions:

17 + 529751 = 529768
59 + 529709 = 529768
131 + 529637 = 529768
149 + 529619 = 529768
191 + 529577 = 529768
251 + 529517 = 529768
347 + 529421 = 529768
419 + 529349 = 529768

Showing the first eight; more decompositions exist.
