Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529812, here are decompositions:

5 + 529807 = 529812
61 + 529751 = 529812
71 + 529741 = 529812
89 + 529723 = 529812
103 + 529709 = 529812
131 + 529681 = 529812
139 + 529673 = 529812
163 + 529649 = 529812

Showing the first eight; more decompositions exist.
