Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168004, here are decompositions:

17 + 167987 = 168004
113 + 167891 = 168004
131 + 167873 = 168004
227 + 167777 = 168004
233 + 167771 = 168004
257 + 167747 = 168004
293 + 167711 = 168004
383 + 167621 = 168004

Showing the first eight; more decompositions exist.
