Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168906, here are decompositions:

5 + 168901 = 168906
7 + 168899 = 168906
13 + 168893 = 168906
19 + 168887 = 168906
37 + 168869 = 168906
43 + 168863 = 168906
103 + 168803 = 168906
137 + 168769 = 168906

Showing the first eight; more decompositions exist.
