Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002128, here are decompositions:

7 + 1002121 = 1002128
19 + 1002109 = 1002128
37 + 1002091 = 1002128
67 + 1002061 = 1002128
79 + 1002049 = 1002128
139 + 1001989 = 1002128
151 + 1001977 = 1002128
181 + 1001947 = 1002128

Showing the first eight; more decompositions exist.
