Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529748, here are decompositions:

7 + 529741 = 529748
61 + 529687 = 529748
67 + 529681 = 529748
229 + 529519 = 529748
277 + 529471 = 529748
337 + 529411 = 529748
367 + 529381 = 529748
421 + 529327 = 529748

Showing the first eight; more decompositions exist.
