Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66908, here are decompositions:

19 + 66889 = 66908
31 + 66877 = 66908
67 + 66841 = 66908
157 + 66751 = 66908
211 + 66697 = 66908
307 + 66601 = 66908
337 + 66571 = 66908
367 + 66541 = 66908

Showing the first eight; more decompositions exist.
