Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529732, here are decompositions:

23 + 529709 = 529732
41 + 529691 = 529732
59 + 529673 = 529732
83 + 529649 = 529732
113 + 529619 = 529732
311 + 529421 = 529732
383 + 529349 = 529732
389 + 529343 = 529732

Showing the first eight; more decompositions exist.
