Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729352, here are decompositions:

19 + 8729333 = 8729352
29 + 8729323 = 8729352
43 + 8729309 = 8729352
61 + 8729291 = 8729352
103 + 8729249 = 8729352
109 + 8729243 = 8729352
113 + 8729239 = 8729352
131 + 8729221 = 8729352

Showing the first eight; more decompositions exist.
