Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518546, here are decompositions:

3 + 518543 = 518546
13 + 518533 = 518546
37 + 518509 = 518546
73 + 518473 = 518546
79 + 518467 = 518546
157 + 518389 = 518546
307 + 518239 = 518546
313 + 518233 = 518546

Showing the first eight; more decompositions exist.
