Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529808, here are decompositions:

61 + 529747 = 529808
67 + 529741 = 529808
127 + 529681 = 529808
151 + 529657 = 529808
229 + 529579 = 529808
277 + 529531 = 529808
337 + 529471 = 529808
397 + 529411 = 529808

Showing the first eight; more decompositions exist.
