Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529820, here are decompositions:

7 + 529813 = 529820
13 + 529807 = 529820
73 + 529747 = 529820
79 + 529741 = 529820
97 + 529723 = 529820
127 + 529693 = 529820
139 + 529681 = 529820
163 + 529657 = 529820

Showing the first eight; more decompositions exist.
