Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727430, here are decompositions:

3 + 8727427 = 8727430
17 + 8727413 = 8727430
71 + 8727359 = 8727430
113 + 8727317 = 8727430
167 + 8727263 = 8727430
233 + 8727197 = 8727430
251 + 8727179 = 8727430
269 + 8727161 = 8727430

Showing the first eight; more decompositions exist.
