Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162126, here are decompositions:

7 + 162119 = 162126
17 + 162109 = 162126
47 + 162079 = 162126
67 + 162059 = 162126
73 + 162053 = 162126
109 + 162017 = 162126
127 + 161999 = 162126
149 + 161977 = 162126

Showing the first eight; more decompositions exist.
