Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513650, here are decompositions:

19 + 513631 = 513650
139 + 513511 = 513650
211 + 513439 = 513650
223 + 513427 = 513650
283 + 513367 = 513650
331 + 513319 = 513650
337 + 513313 = 513650
367 + 513283 = 513650

Showing the first eight; more decompositions exist.
