Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167920, here are decompositions:

3 + 167917 = 167920
29 + 167891 = 167920
41 + 167879 = 167920
47 + 167873 = 167920
59 + 167861 = 167920
149 + 167771 = 167920
173 + 167747 = 167920
191 + 167729 = 167920

Showing the first eight; more decompositions exist.
