Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162170, here are decompositions:

61 + 162109 = 162170
79 + 162091 = 162170
163 + 162007 = 162170
193 + 161977 = 162170
199 + 161971 = 162170
223 + 161947 = 162170
331 + 161839 = 162170
397 + 161773 = 162170

Showing the first eight; more decompositions exist.
