Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66884, here are decompositions:

7 + 66877 = 66884
31 + 66853 = 66884
43 + 66841 = 66884
151 + 66733 = 66884
163 + 66721 = 66884
241 + 66643 = 66884
283 + 66601 = 66884
313 + 66571 = 66884

Showing the first eight; more decompositions exist.
