Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518732, here are decompositions:

3 + 518729 = 518732
43 + 518689 = 518732
199 + 518533 = 518732
211 + 518521 = 518732
223 + 518509 = 518732
421 + 518311 = 518732
433 + 518299 = 518732
499 + 518233 = 518732

Showing the first eight; more decompositions exist.
