Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529986, here are decompositions:

5 + 529981 = 529986
7 + 529979 = 529986
13 + 529973 = 529986
29 + 529957 = 529986
47 + 529939 = 529986
53 + 529933 = 529986
59 + 529927 = 529986
139 + 529847 = 529986

Showing the first eight; more decompositions exist.
