Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518480, here are decompositions:

7 + 518473 = 518480
13 + 518467 = 518480
139 + 518341 = 518480
181 + 518299 = 518480
241 + 518239 = 518480
271 + 518209 = 518480
349 + 518131 = 518480
367 + 518113 = 518480

Showing the first eight; more decompositions exist.
