Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009138, here are decompositions:

17 + 1009121 = 1009138
41 + 1009097 = 1009138
89 + 1009049 = 1009138
101 + 1009037 = 1009138
131 + 1009007 = 1009138
149 + 1008989 = 1009138
191 + 1008947 = 1009138
227 + 1008911 = 1009138

Showing the first eight; more decompositions exist.
