Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66988, here are decompositions:

11 + 66977 = 66988
29 + 66959 = 66988
41 + 66947 = 66988
137 + 66851 = 66988
167 + 66821 = 66988
179 + 66809 = 66988
191 + 66797 = 66988
197 + 66791 = 66988

Showing the first eight; more decompositions exist.
