Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529542, here are decompositions:

11 + 529531 = 529542
23 + 529519 = 529542
29 + 529513 = 529542
53 + 529489 = 529542
71 + 529471 = 529542
131 + 529411 = 529542
149 + 529393 = 529542
193 + 529349 = 529542

Showing the first eight; more decompositions exist.
