Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529990, here are decompositions:

3 + 529987 = 529990
11 + 529979 = 529990
17 + 529973 = 529990
29 + 529961 = 529990
179 + 529811 = 529990
239 + 529751 = 529990
281 + 529709 = 529990
317 + 529673 = 529990

Showing the first eight; more decompositions exist.
