Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158868, here are decompositions:

5 + 158863 = 158868
19 + 158849 = 158868
97 + 158771 = 158868
107 + 158761 = 158868
109 + 158759 = 158868
137 + 158731 = 158868
211 + 158657 = 158868
251 + 158617 = 158868

Showing the first eight; more decompositions exist.
