Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66810, here are decompositions:

13 + 66797 = 66810
19 + 66791 = 66810
47 + 66763 = 66810
59 + 66751 = 66810
61 + 66749 = 66810
71 + 66739 = 66810
89 + 66721 = 66810
97 + 66713 = 66810

Showing the first eight; more decompositions exist.
