Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66846, here are decompositions:

5 + 66841 = 66846
37 + 66809 = 66846
83 + 66763 = 66846
97 + 66749 = 66846
107 + 66739 = 66846
113 + 66733 = 66846
149 + 66697 = 66846
163 + 66683 = 66846

Showing the first eight; more decompositions exist.
