Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168008, here are decompositions:

37 + 167971 = 168008
97 + 167911 = 168008
109 + 167899 = 168008
199 + 167809 = 168008
229 + 167779 = 168008
331 + 167677 = 168008
367 + 167641 = 168008
397 + 167611 = 168008

Showing the first eight; more decompositions exist.
