Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518458, here are decompositions:

11 + 518447 = 518458
29 + 518429 = 518458
41 + 518417 = 518458
47 + 518411 = 518458
71 + 518387 = 518458
131 + 518327 = 518458
167 + 518291 = 518458
197 + 518261 = 518458

Showing the first eight; more decompositions exist.
