Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518560, here are decompositions:

17 + 518543 = 518560
89 + 518471 = 518560
113 + 518447 = 518560
131 + 518429 = 518560
149 + 518411 = 518560
173 + 518387 = 518560
233 + 518327 = 518560
269 + 518291 = 518560

Showing the first eight; more decompositions exist.
