Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518694, here are decompositions:

5 + 518689 = 518694
37 + 518657 = 518694
73 + 518621 = 518694
83 + 518611 = 518694
97 + 518597 = 518694
107 + 518587 = 518694
151 + 518543 = 518694
173 + 518521 = 518694

Showing the first eight; more decompositions exist.
