Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008158, here are decompositions:

127 + 1008031 = 1008158
157 + 1008001 = 1008158
181 + 1007977 = 1008158
199 + 1007959 = 1008158
271 + 1007887 = 1008158
331 + 1007827 = 1008158
409 + 1007749 = 1008158
439 + 1007719 = 1008158

Showing the first eight; more decompositions exist.
