Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756158, here are decompositions:

29 + 8756129 = 8756158
41 + 8756117 = 8756158
107 + 8756051 = 8756158
137 + 8756021 = 8756158
149 + 8756009 = 8756158
167 + 8755991 = 8756158
269 + 8755889 = 8756158
317 + 8755841 = 8756158

Showing the first eight; more decompositions exist.
