Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529380, here are decompositions:

23 + 529357 = 529380
31 + 529349 = 529380
37 + 529343 = 529380
53 + 529327 = 529380
67 + 529313 = 529380
73 + 529307 = 529380
79 + 529301 = 529380
107 + 529273 = 529380

Showing the first eight; more decompositions exist.
