Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529490, here are decompositions:

19 + 529471 = 529490
67 + 529423 = 529490
79 + 529411 = 529490
97 + 529393 = 529490
109 + 529381 = 529490
163 + 529327 = 529490
277 + 529213 = 529490
307 + 529183 = 529490

Showing the first eight; more decompositions exist.
