Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529520, here are decompositions:

3 + 529517 = 529520
7 + 529513 = 529520
31 + 529489 = 529520
97 + 529423 = 529520
109 + 529411 = 529520
127 + 529393 = 529520
139 + 529381 = 529520
163 + 529357 = 529520

Showing the first eight; more decompositions exist.
