Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20168, here are decompositions:

7 + 20161 = 20168
19 + 20149 = 20168
61 + 20107 = 20168
67 + 20101 = 20168
79 + 20089 = 20168
97 + 20071 = 20168
139 + 20029 = 20168
157 + 20011 = 20168

Showing the first eight; more decompositions exist.
