Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158226, here are decompositions:

17 + 158209 = 158226
37 + 158189 = 158226
83 + 158143 = 158226
97 + 158129 = 158226
113 + 158113 = 158226
149 + 158077 = 158226
179 + 158047 = 158226
197 + 158029 = 158226

Showing the first eight; more decompositions exist.
