Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508978, here are decompositions:

5 + 508973 = 508978
17 + 508961 = 508978
47 + 508931 = 508978
59 + 508919 = 508978
131 + 508847 = 508978
137 + 508841 = 508978
167 + 508811 = 508978
179 + 508799 = 508978

Showing the first eight; more decompositions exist.
