Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66860, here are decompositions:

7 + 66853 = 66860
19 + 66841 = 66860
97 + 66763 = 66860
109 + 66751 = 66860
127 + 66733 = 66860
139 + 66721 = 66860
163 + 66697 = 66860
307 + 66553 = 66860

Showing the first eight; more decompositions exist.
