Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66976, here are decompositions:

3 + 66973 = 66976
17 + 66959 = 66976
29 + 66947 = 66976
53 + 66923 = 66976
113 + 66863 = 66976
167 + 66809 = 66976
179 + 66797 = 66976
227 + 66749 = 66976

Showing the first eight; more decompositions exist.
