Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162210, here are decompositions:

67 + 162143 = 162210
101 + 162109 = 162210
131 + 162079 = 162210
151 + 162059 = 162210
157 + 162053 = 162210
193 + 162017 = 162210
199 + 162011 = 162210
211 + 161999 = 162210

Showing the first eight; more decompositions exist.
