Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523208, here are decompositions:

31 + 523177 = 523208
79 + 523129 = 523208
337 + 522871 = 523208
379 + 522829 = 523208
397 + 522811 = 523208
421 + 522787 = 523208
547 + 522661 = 523208
571 + 522637 = 523208

Showing the first eight; more decompositions exist.
