Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529900, here are decompositions:

29 + 529871 = 529900
53 + 529847 = 529900
71 + 529829 = 529900
89 + 529811 = 529900
149 + 529751 = 529900
191 + 529709 = 529900
227 + 529673 = 529900
251 + 529649 = 529900

Showing the first eight; more decompositions exist.
