Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40008, here are decompositions:

19 + 39989 = 40008
29 + 39979 = 40008
37 + 39971 = 40008
71 + 39937 = 40008
79 + 39929 = 40008
107 + 39901 = 40008
131 + 39877 = 40008
139 + 39869 = 40008

Showing the first eight; more decompositions exist.
