Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513644, here are decompositions:

3 + 513641 = 513644
13 + 513631 = 513644
163 + 513481 = 513644
277 + 513367 = 513644
331 + 513313 = 513644
337 + 513307 = 513644
367 + 513277 = 513644
487 + 513157 = 513644

Showing the first eight; more decompositions exist.
