Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009188, here are decompositions:

29 + 1009159 = 1009188
31 + 1009157 = 1009188
67 + 1009121 = 1009188
127 + 1009061 = 1009188
139 + 1009049 = 1009188
151 + 1009037 = 1009188
181 + 1009007 = 1009188
197 + 1008991 = 1009188

Showing the first eight; more decompositions exist.
