Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513542, here are decompositions:

13 + 513529 = 513542
31 + 513511 = 513542
61 + 513481 = 513542
103 + 513439 = 513542
223 + 513319 = 513542
229 + 513313 = 513542
373 + 513169 = 513542
433 + 513109 = 513542

Showing the first eight; more decompositions exist.
