Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167906, here are decompositions:

7 + 167899 = 167906
19 + 167887 = 167906
43 + 167863 = 167906
97 + 167809 = 167906
127 + 167779 = 167906
223 + 167683 = 167906
229 + 167677 = 167906
283 + 167623 = 167906

Showing the first eight; more decompositions exist.
