Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729436, here are decompositions:

7 + 8729429 = 8729436
47 + 8729389 = 8729436
103 + 8729333 = 8729436
109 + 8729327 = 8729436
113 + 8729323 = 8729436
127 + 8729309 = 8729436
193 + 8729243 = 8729436
197 + 8729239 = 8729436

Showing the first eight; more decompositions exist.
