Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518670, here are decompositions:

13 + 518657 = 518670
59 + 518611 = 518670
73 + 518597 = 518670
83 + 518587 = 518670
127 + 518543 = 518670
137 + 518533 = 518670
149 + 518521 = 518670
197 + 518473 = 518670

Showing the first eight; more decompositions exist.
