Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515670, here are decompositions:

7 + 515663 = 515670
17 + 515653 = 515670
19 + 515651 = 515670
31 + 515639 = 515670
59 + 515611 = 515670
73 + 515597 = 515670
83 + 515587 = 515670
107 + 515563 = 515670

Showing the first eight; more decompositions exist.
