Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518662, here are decompositions:

5 + 518657 = 518662
41 + 518621 = 518662
83 + 518579 = 518662
191 + 518471 = 518662
233 + 518429 = 518662
251 + 518411 = 518662
401 + 518261 = 518662
491 + 518171 = 518662

Showing the first eight; more decompositions exist.
