Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002188, here are decompositions:

37 + 1002151 = 1002188
67 + 1002121 = 1002188
79 + 1002109 = 1002188
97 + 1002091 = 1002188
127 + 1002061 = 1002188
139 + 1002049 = 1002188
199 + 1001989 = 1002188
211 + 1001977 = 1002188

Showing the first eight; more decompositions exist.
