Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727442, here are decompositions:

11 + 8727431 = 8727442
29 + 8727413 = 8727442
83 + 8727359 = 8727442
173 + 8727269 = 8727442
179 + 8727263 = 8727442
263 + 8727179 = 8727442
281 + 8727161 = 8727442
293 + 8727149 = 8727442

Showing the first eight; more decompositions exist.
