Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518476, here are decompositions:

3 + 518473 = 518476
5 + 518471 = 518476
29 + 518447 = 518476
47 + 518429 = 518476
59 + 518417 = 518476
89 + 518387 = 518476
149 + 518327 = 518476
227 + 518249 = 518476

Showing the first eight; more decompositions exist.
