Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162008, here are decompositions:

31 + 161977 = 162008
37 + 161971 = 162008
61 + 161947 = 162008
97 + 161911 = 162008
127 + 161881 = 162008
139 + 161869 = 162008
229 + 161779 = 162008
277 + 161731 = 162008

Showing the first eight; more decompositions exist.
