Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518746, here are decompositions:

3 + 518743 = 518746
5 + 518741 = 518746
17 + 518729 = 518746
29 + 518717 = 518746
47 + 518699 = 518746
89 + 518657 = 518746
149 + 518597 = 518746
167 + 518579 = 518746

Showing the first eight; more decompositions exist.
