Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162164, here are decompositions:

73 + 162091 = 162164
157 + 162007 = 162164
181 + 161983 = 162164
193 + 161971 = 162164
241 + 161923 = 162164
283 + 161881 = 162164
421 + 161743 = 162164
433 + 161731 = 162164

Showing the first eight; more decompositions exist.
