Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508918, here are decompositions:

5 + 508913 = 508918
17 + 508901 = 508918
71 + 508847 = 508918
101 + 508817 = 508918
107 + 508811 = 508918
191 + 508727 = 508918
257 + 508661 = 508918
281 + 508637 = 508918

Showing the first eight; more decompositions exist.
