Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516942, here are decompositions:

11 + 516931 = 516942
31 + 516911 = 516942
59 + 516883 = 516942
71 + 516871 = 516942
103 + 516839 = 516942
113 + 516829 = 516942
131 + 516811 = 516942
149 + 516793 = 516942

Showing the first eight; more decompositions exist.
