Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516636, here are decompositions:

13 + 516623 = 516636
17 + 516619 = 516636
19 + 516617 = 516636
37 + 516599 = 516636
47 + 516589 = 516636
73 + 516563 = 516636
97 + 516539 = 516636
137 + 516499 = 516636

Showing the first eight; more decompositions exist.
