Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518744, here are decompositions:

3 + 518741 = 518744
7 + 518737 = 518744
157 + 518587 = 518744
211 + 518533 = 518744
223 + 518521 = 518744
271 + 518473 = 518744
277 + 518467 = 518744
313 + 518431 = 518744

Showing the first eight; more decompositions exist.
