Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729338, here are decompositions:

5 + 8729333 = 8729338
11 + 8729327 = 8729338
29 + 8729309 = 8729338
47 + 8729291 = 8729338
89 + 8729249 = 8729338
131 + 8729207 = 8729338
197 + 8729141 = 8729338
239 + 8729099 = 8729338

Showing the first eight; more decompositions exist.
