Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515658, here are decompositions:

5 + 515653 = 515658
7 + 515651 = 515658
19 + 515639 = 515658
37 + 515621 = 515658
47 + 515611 = 515658
61 + 515597 = 515658
71 + 515587 = 515658
79 + 515579 = 515658

Showing the first eight; more decompositions exist.
