Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729488, here are decompositions:

59 + 8729429 = 8729488
179 + 8729309 = 8729488
197 + 8729291 = 8729488
239 + 8729249 = 8729488
269 + 8729219 = 8729488
281 + 8729207 = 8729488
347 + 8729141 = 8729488
389 + 8729099 = 8729488

Showing the first eight; more decompositions exist.
