Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162270, here are decompositions:

7 + 162263 = 162270
13 + 162257 = 162270
19 + 162251 = 162270
41 + 162229 = 162270
61 + 162209 = 162270
127 + 162143 = 162270
151 + 162119 = 162270
179 + 162091 = 162270

Showing the first eight; more decompositions exist.
