Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518018, here are decompositions:

19 + 517999 = 518018
37 + 517981 = 518018
157 + 517861 = 518018
271 + 517747 = 518018
307 + 517711 = 518018
379 + 517639 = 518018
409 + 517609 = 518018
421 + 517597 = 518018

Showing the first eight; more decompositions exist.
