Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529440, here are decompositions:

17 + 529423 = 529440
19 + 529421 = 529440
29 + 529411 = 529440
47 + 529393 = 529440
59 + 529381 = 529440
83 + 529357 = 529440
97 + 529343 = 529440
113 + 529327 = 529440

Showing the first eight; more decompositions exist.
