Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529784, here are decompositions:

37 + 529747 = 529784
43 + 529741 = 529784
61 + 529723 = 529784
97 + 529687 = 529784
103 + 529681 = 529784
127 + 529657 = 529784
181 + 529603 = 529784
271 + 529513 = 529784

Showing the first eight; more decompositions exist.
