Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11908, here are decompositions:

5 + 11903 = 11908
11 + 11897 = 11908
41 + 11867 = 11908
101 + 11807 = 11908
107 + 11801 = 11908
131 + 11777 = 11908
191 + 11717 = 11908
227 + 11681 = 11908

Showing the first eight; more decompositions exist.
