Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518532, here are decompositions:

11 + 518521 = 518532
23 + 518509 = 518532
59 + 518473 = 518532
61 + 518471 = 518532
101 + 518431 = 518532
103 + 518429 = 518532
191 + 518341 = 518532
233 + 518299 = 518532

Showing the first eight; more decompositions exist.
