Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162144, here are decompositions:

53 + 162091 = 162144
127 + 162017 = 162144
137 + 162007 = 162144
167 + 161977 = 162144
173 + 161971 = 162144
197 + 161947 = 162144
223 + 161921 = 162144
233 + 161911 = 162144

Showing the first eight; more decompositions exist.
