Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529866, here are decompositions:

19 + 529847 = 529866
37 + 529829 = 529866
47 + 529819 = 529866
53 + 529813 = 529866
59 + 529807 = 529866
157 + 529709 = 529866
173 + 529693 = 529866
179 + 529687 = 529866

Showing the first eight; more decompositions exist.
