Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516628, here are decompositions:

5 + 516623 = 516628
11 + 516617 = 516628
17 + 516611 = 516628
29 + 516599 = 516628
41 + 516587 = 516628
89 + 516539 = 516628
107 + 516521 = 516628
179 + 516449 = 516628

Showing the first eight; more decompositions exist.
