Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529686, here are decompositions:

5 + 529681 = 529686
13 + 529673 = 529686
29 + 529657 = 529686
37 + 529649 = 529686
67 + 529619 = 529686
83 + 529603 = 529686
107 + 529579 = 529686
109 + 529577 = 529686

Showing the first eight; more decompositions exist.
