Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66814, here are decompositions:

5 + 66809 = 66814
17 + 66797 = 66814
23 + 66791 = 66814
101 + 66713 = 66814
113 + 66701 = 66814
131 + 66683 = 66814
197 + 66617 = 66814
227 + 66587 = 66814

Showing the first eight; more decompositions exist.
