Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729250, here are decompositions:

7 + 8729243 = 8729250
11 + 8729239 = 8729250
29 + 8729221 = 8729250
31 + 8729219 = 8729250
43 + 8729207 = 8729250
59 + 8729191 = 8729250
67 + 8729183 = 8729250
71 + 8729179 = 8729250

Showing the first eight; more decompositions exist.
