Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729290, here are decompositions:

41 + 8729249 = 8729290
47 + 8729243 = 8729290
71 + 8729219 = 8729290
83 + 8729207 = 8729290
107 + 8729183 = 8729290
149 + 8729141 = 8729290
173 + 8729117 = 8729290
191 + 8729099 = 8729290

Showing the first eight; more decompositions exist.
