Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518448, here are decompositions:

17 + 518431 = 518448
19 + 518429 = 518448
31 + 518417 = 518448
37 + 518411 = 518448
59 + 518389 = 518448
61 + 518387 = 518448
107 + 518341 = 518448
137 + 518311 = 518448

Showing the first eight; more decompositions exist.
