Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506878, here are decompositions:

5 + 506873 = 506878
17 + 506861 = 506878
41 + 506837 = 506878
149 + 506729 = 506878
179 + 506699 = 506878
191 + 506687 = 506878
269 + 506609 = 506878
347 + 506531 = 506878

Showing the first eight; more decompositions exist.
