Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518502, here are decompositions:

29 + 518473 = 518502
31 + 518471 = 518502
71 + 518431 = 518502
73 + 518429 = 518502
113 + 518389 = 518502
191 + 518311 = 518502
211 + 518291 = 518502
241 + 518261 = 518502

Showing the first eight; more decompositions exist.
