Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529856, here are decompositions:

37 + 529819 = 529856
43 + 529813 = 529856
109 + 529747 = 529856
163 + 529693 = 529856
199 + 529657 = 529856
277 + 529579 = 529856
337 + 529519 = 529856
367 + 529489 = 529856

Showing the first eight; more decompositions exist.
