Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529680, here are decompositions:

7 + 529673 = 529680
23 + 529657 = 529680
31 + 529649 = 529680
43 + 529637 = 529680
61 + 529619 = 529680
101 + 529579 = 529680
103 + 529577 = 529680
149 + 529531 = 529680

Showing the first eight; more decompositions exist.
