Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136906, here are decompositions:

17 + 136889 = 136906
23 + 136883 = 136906
47 + 136859 = 136906
137 + 136769 = 136906
167 + 136739 = 136906
173 + 136733 = 136906
179 + 136727 = 136906
197 + 136709 = 136906

Showing the first eight; more decompositions exist.
