Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518460, here are decompositions:

13 + 518447 = 518460
29 + 518431 = 518460
31 + 518429 = 518460
43 + 518417 = 518460
71 + 518389 = 518460
73 + 518387 = 518460
149 + 518311 = 518460
199 + 518261 = 518460

Showing the first eight; more decompositions exist.
