Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729458, here are decompositions:

29 + 8729429 = 8729458
47 + 8729411 = 8729458
131 + 8729327 = 8729458
149 + 8729309 = 8729458
167 + 8729291 = 8729458
239 + 8729219 = 8729458
251 + 8729207 = 8729458
317 + 8729141 = 8729458

Showing the first eight; more decompositions exist.
