Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529868, here are decompositions:

61 + 529807 = 529868
127 + 529741 = 529868
181 + 529687 = 529868
211 + 529657 = 529868
337 + 529531 = 529868
349 + 529519 = 529868
379 + 529489 = 529868
397 + 529471 = 529868

Showing the first eight; more decompositions exist.
