Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009198, here are decompositions:

5 + 1009193 = 1009198
41 + 1009157 = 1009198
59 + 1009139 = 1009198
101 + 1009097 = 1009198
137 + 1009061 = 1009198
149 + 1009049 = 1009198
191 + 1009007 = 1009198
251 + 1008947 = 1009198

Showing the first eight; more decompositions exist.
