Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18948, here are decompositions:

29 + 18919 = 18948
31 + 18917 = 18948
37 + 18911 = 18948
79 + 18869 = 18948
89 + 18859 = 18948
109 + 18839 = 18948
151 + 18797 = 18948
191 + 18757 = 18948

Showing the first eight; more decompositions exist.
