Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729398, here are decompositions:

71 + 8729327 = 8729398
89 + 8729309 = 8729398
107 + 8729291 = 8729398
149 + 8729249 = 8729398
179 + 8729219 = 8729398
191 + 8729207 = 8729398
257 + 8729141 = 8729398
281 + 8729117 = 8729398

Showing the first eight; more decompositions exist.
