Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148908, here are decompositions:

17 + 148891 = 148908
41 + 148867 = 148908
47 + 148861 = 148908
79 + 148829 = 148908
127 + 148781 = 148908
181 + 148727 = 148908
197 + 148711 = 148908
239 + 148669 = 148908

Showing the first eight; more decompositions exist.
