Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009128, here are decompositions:

7 + 1009121 = 1009128
31 + 1009097 = 1009128
67 + 1009061 = 1009128
79 + 1009049 = 1009128
137 + 1008991 = 1009128
139 + 1008989 = 1009128
149 + 1008979 = 1009128
181 + 1008947 = 1009128

Showing the first eight; more decompositions exist.
