Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158156, here are decompositions:

13 + 158143 = 158156
43 + 158113 = 158156
79 + 158077 = 158156
109 + 158047 = 158156
127 + 158029 = 158156
139 + 158017 = 158156
157 + 157999 = 158156
223 + 157933 = 158156

Showing the first eight; more decompositions exist.
