Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727646, here are decompositions:

3 + 8727643 = 8727646
23 + 8727623 = 8727646
47 + 8727599 = 8727646
107 + 8727539 = 8727646
149 + 8727497 = 8727646
233 + 8727413 = 8727646
359 + 8727287 = 8727646
383 + 8727263 = 8727646

Showing the first eight; more decompositions exist.
