Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727628, here are decompositions:

5 + 8727623 = 8727628
17 + 8727611 = 8727628
29 + 8727599 = 8727628
59 + 8727569 = 8727628
89 + 8727539 = 8727628
131 + 8727497 = 8727628
197 + 8727431 = 8727628
269 + 8727359 = 8727628

Showing the first eight; more decompositions exist.
