Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13008, here are decompositions:

5 + 13003 = 13008
7 + 13001 = 13008
29 + 12979 = 13008
41 + 12967 = 13008
67 + 12941 = 13008
89 + 12919 = 13008
97 + 12911 = 13008
101 + 12907 = 13008

Showing the first eight; more decompositions exist.
