Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516630, here are decompositions:

7 + 516623 = 516630
11 + 516619 = 516630
13 + 516617 = 516630
19 + 516611 = 516630
31 + 516599 = 516630
41 + 516589 = 516630
43 + 516587 = 516630
67 + 516563 = 516630

Showing the first eight; more decompositions exist.
