Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30908, here are decompositions:

37 + 30871 = 30908
67 + 30841 = 30908
79 + 30829 = 30908
127 + 30781 = 30908
151 + 30757 = 30908
181 + 30727 = 30908
211 + 30697 = 30908
271 + 30637 = 30908

Showing the first eight; more decompositions exist.
