Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529988, here are decompositions:

7 + 529981 = 529988
31 + 529957 = 529988
61 + 529927 = 529988
181 + 529807 = 529988
241 + 529747 = 529988
307 + 529681 = 529988
331 + 529657 = 529988
409 + 529579 = 529988

Showing the first eight; more decompositions exist.
