Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164170, here are decompositions:

23 + 164147 = 164170
53 + 164117 = 164170
113 + 164057 = 164170
131 + 164039 = 164170
173 + 163997 = 164170
179 + 163991 = 164170
191 + 163979 = 164170
197 + 163973 = 164170

Showing the first eight; more decompositions exist.
