Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127158, here are decompositions:

19 + 127139 = 127158
79 + 127079 = 127158
107 + 127051 = 127158
127 + 127031 = 127158
191 + 126967 = 127158
197 + 126961 = 127158
307 + 126851 = 127158
331 + 126827 = 127158

Showing the first eight; more decompositions exist.
