Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529538, here are decompositions:

7 + 529531 = 529538
19 + 529519 = 529538
67 + 529471 = 529538
127 + 529411 = 529538
157 + 529381 = 529538
181 + 529357 = 529538
211 + 529327 = 529538
409 + 529129 = 529538

Showing the first eight; more decompositions exist.
