Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518526, here are decompositions:

5 + 518521 = 518526
17 + 518509 = 518526
53 + 518473 = 518526
59 + 518467 = 518526
79 + 518447 = 518526
97 + 518429 = 518526
109 + 518417 = 518526
137 + 518389 = 518526

Showing the first eight; more decompositions exist.
