Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506866, here are decompositions:

5 + 506861 = 506866
23 + 506843 = 506866
29 + 506837 = 506866
83 + 506783 = 506866
137 + 506729 = 506866
167 + 506699 = 506866
179 + 506687 = 506866
257 + 506609 = 506866

Showing the first eight; more decompositions exist.
