Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164166, here are decompositions:

17 + 164149 = 164166
19 + 164147 = 164166
53 + 164113 = 164166
73 + 164093 = 164166
109 + 164057 = 164166
127 + 164039 = 164166
173 + 163993 = 164166
179 + 163987 = 164166

Showing the first eight; more decompositions exist.
