Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729476, here are decompositions:

47 + 8729429 = 8729476
149 + 8729327 = 8729476
167 + 8729309 = 8729476
227 + 8729249 = 8729476
233 + 8729243 = 8729476
257 + 8729219 = 8729476
269 + 8729207 = 8729476
293 + 8729183 = 8729476

Showing the first eight; more decompositions exist.
