Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009158, here are decompositions:

5 + 1009153 = 1009158
19 + 1009139 = 1009158
37 + 1009121 = 1009158
61 + 1009097 = 1009158
97 + 1009061 = 1009158
109 + 1009049 = 1009158
151 + 1009007 = 1009158
167 + 1008991 = 1009158

Showing the first eight; more decompositions exist.
