Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518550, here are decompositions:

7 + 518543 = 518550
17 + 518533 = 518550
29 + 518521 = 518550
41 + 518509 = 518550
79 + 518471 = 518550
83 + 518467 = 518550
103 + 518447 = 518550
139 + 518411 = 518550

Showing the first eight; more decompositions exist.
