Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727418, here are decompositions:

5 + 8727413 = 8727418
59 + 8727359 = 8727418
101 + 8727317 = 8727418
131 + 8727287 = 8727418
149 + 8727269 = 8727418
239 + 8727179 = 8727418
257 + 8727161 = 8727418
269 + 8727149 = 8727418

Showing the first eight; more decompositions exist.
