Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66888, here are decompositions:

5 + 66883 = 66888
11 + 66877 = 66888
37 + 66851 = 66888
47 + 66841 = 66888
67 + 66821 = 66888
79 + 66809 = 66888
97 + 66791 = 66888
137 + 66751 = 66888

Showing the first eight; more decompositions exist.
