Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188908, here are decompositions:

17 + 188891 = 188908
47 + 188861 = 188908
107 + 188801 = 188908
179 + 188729 = 188908
197 + 188711 = 188908
227 + 188681 = 188908
389 + 188519 = 188908
449 + 188459 = 188908

Showing the first eight; more decompositions exist.
