Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729650, here are decompositions:

3 + 8729647 = 8729650
29 + 8729621 = 8729650
47 + 8729603 = 8729650
107 + 8729543 = 8729650
239 + 8729411 = 8729650
317 + 8729333 = 8729650
359 + 8729291 = 8729650
401 + 8729249 = 8729650

Showing the first eight; more decompositions exist.
