Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162012, here are decompositions:

5 + 162007 = 162012
13 + 161999 = 162012
29 + 161983 = 162012
41 + 161971 = 162012
43 + 161969 = 162012
89 + 161923 = 162012
101 + 161911 = 162012
131 + 161881 = 162012

Showing the first eight; more decompositions exist.
