Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168040, here are decompositions:

3 + 168037 = 168040
11 + 168029 = 168040
17 + 168023 = 168040
53 + 167987 = 168040
149 + 167891 = 168040
167 + 167873 = 168040
179 + 167861 = 168040
239 + 167801 = 168040

Showing the first eight; more decompositions exist.
