Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513516, here are decompositions:

5 + 513511 = 513516
7 + 513509 = 513516
37 + 513479 = 513516
43 + 513473 = 513516
89 + 513427 = 513516
97 + 513419 = 513516
109 + 513407 = 513516
149 + 513367 = 513516

Showing the first eight; more decompositions exist.
