Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729298, here are decompositions:

7 + 8729291 = 8729298
59 + 8729239 = 8729298
79 + 8729219 = 8729298
107 + 8729191 = 8729298
157 + 8729141 = 8729298
167 + 8729131 = 8729298
181 + 8729117 = 8729298
191 + 8729107 = 8729298

Showing the first eight; more decompositions exist.
