Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20156, here are decompositions:

7 + 20149 = 20156
13 + 20143 = 20156
43 + 20113 = 20156
67 + 20089 = 20156
109 + 20047 = 20156
127 + 20029 = 20156
163 + 19993 = 20156
193 + 19963 = 20156

Showing the first eight; more decompositions exist.
