Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002158, here are decompositions:

7 + 1002151 = 1002158
37 + 1002121 = 1002158
67 + 1002091 = 1002158
97 + 1002061 = 1002158
109 + 1002049 = 1002158
181 + 1001977 = 1002158
211 + 1001947 = 1002158
337 + 1001821 = 1002158

Showing the first eight; more decompositions exist.
