Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709198, here are decompositions:

7 + 8709191 = 8709198
11 + 8709187 = 8709198
59 + 8709139 = 8709198
131 + 8709067 = 8709198
139 + 8709059 = 8709198
191 + 8709007 = 8709198
227 + 8708971 = 8709198
229 + 8708969 = 8709198

Showing the first eight; more decompositions exist.
