Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66850, here are decompositions:

29 + 66821 = 66850
41 + 66809 = 66850
53 + 66797 = 66850
59 + 66791 = 66850
101 + 66749 = 66850
137 + 66713 = 66850
149 + 66701 = 66850
167 + 66683 = 66850

Showing the first eight; more decompositions exist.
