Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516972, here are decompositions:

13 + 516959 = 516972
23 + 516949 = 516972
41 + 516931 = 516972
61 + 516911 = 516972
89 + 516883 = 516972
101 + 516871 = 516972
151 + 516821 = 516972
179 + 516793 = 516972

Showing the first eight; more decompositions exist.
