Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001158, here are decompositions:

5 + 1001153 = 1001158
71 + 1001087 = 1001158
89 + 1001069 = 1001158
131 + 1001027 = 1001158
227 + 1000931 = 1001158
239 + 1000919 = 1001158
251 + 1000907 = 1001158
269 + 1000889 = 1001158

Showing the first eight; more decompositions exist.
