Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66994, here are decompositions:

17 + 66977 = 66994
47 + 66947 = 66994
71 + 66923 = 66994
131 + 66863 = 66994
173 + 66821 = 66994
197 + 66797 = 66994
281 + 66713 = 66994
293 + 66701 = 66994

Showing the first eight; more decompositions exist.
