Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162150, here are decompositions:

7 + 162143 = 162150
31 + 162119 = 162150
41 + 162109 = 162150
59 + 162091 = 162150
71 + 162079 = 162150
97 + 162053 = 162150
139 + 162011 = 162150
151 + 161999 = 162150

Showing the first eight; more decompositions exist.
