Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168012, here are decompositions:

41 + 167971 = 168012
59 + 167953 = 168012
101 + 167911 = 168012
113 + 167899 = 168012
139 + 167873 = 168012
149 + 167863 = 168012
151 + 167861 = 168012
211 + 167801 = 168012

Showing the first eight; more decompositions exist.
