Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169888, here are decompositions:

29 + 169859 = 169888
71 + 169817 = 169888
137 + 169751 = 169888
179 + 169709 = 169888
197 + 169691 = 169888
227 + 169661 = 169888
239 + 169649 = 169888
281 + 169607 = 169888

Showing the first eight; more decompositions exist.
