Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72008, here are decompositions:

37 + 71971 = 72008
61 + 71947 = 72008
67 + 71941 = 72008
109 + 71899 = 72008
127 + 71881 = 72008
199 + 71809 = 72008
337 + 71671 = 72008
439 + 71569 = 72008

Showing the first eight; more decompositions exist.
