Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755158, here are decompositions:

17 + 8755141 = 8755158
37 + 8755121 = 8755158
79 + 8755079 = 8755158
109 + 8755049 = 8755158
127 + 8755031 = 8755158
131 + 8755027 = 8755158
157 + 8755001 = 8755158
179 + 8754979 = 8755158

Showing the first eight; more decompositions exist.
