Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516880, here are decompositions:

3 + 516877 = 516880
41 + 516839 = 516880
59 + 516821 = 516880
167 + 516713 = 516880
179 + 516701 = 516880
191 + 516689 = 516880
227 + 516653 = 516880
257 + 516623 = 516880

Showing the first eight; more decompositions exist.
