Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30008, here are decompositions:

19 + 29989 = 30008
61 + 29947 = 30008
127 + 29881 = 30008
157 + 29851 = 30008
337 + 29671 = 30008
367 + 29641 = 30008
379 + 29629 = 30008
397 + 29611 = 30008

Showing the first eight; more decompositions exist.
