Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513524, here are decompositions:

13 + 513511 = 513524
43 + 513481 = 513524
97 + 513427 = 513524
127 + 513397 = 513524
157 + 513367 = 513524
211 + 513313 = 513524
241 + 513283 = 513524
367 + 513157 = 513524

Showing the first eight; more decompositions exist.
