Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729262, here are decompositions:

13 + 8729249 = 8729262
19 + 8729243 = 8729262
23 + 8729239 = 8729262
41 + 8729221 = 8729262
43 + 8729219 = 8729262
71 + 8729191 = 8729262
79 + 8729183 = 8729262
83 + 8729179 = 8729262

Showing the first eight; more decompositions exist.
