Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729340, here are decompositions:

7 + 8729333 = 8729340
13 + 8729327 = 8729340
17 + 8729323 = 8729340
23 + 8729317 = 8729340
31 + 8729309 = 8729340
97 + 8729243 = 8729340
101 + 8729239 = 8729340
149 + 8729191 = 8729340

Showing the first eight; more decompositions exist.
