Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513632, here are decompositions:

103 + 513529 = 513632
151 + 513481 = 513632
193 + 513439 = 513632
313 + 513319 = 513632
349 + 513283 = 513632
463 + 513169 = 513632
523 + 513109 = 513632
601 + 513031 = 513632

Showing the first eight; more decompositions exist.
