Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518706, here are decompositions:

7 + 518699 = 518706
17 + 518689 = 518706
109 + 518597 = 518706
127 + 518579 = 518706
163 + 518543 = 518706
173 + 518533 = 518706
197 + 518509 = 518706
233 + 518473 = 518706

Showing the first eight; more decompositions exist.
