Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728018, here are decompositions:

29 + 8727989 = 8728018
227 + 8727791 = 8728018
239 + 8727779 = 8728018
251 + 8727767 = 8728018
317 + 8727701 = 8728018
359 + 8727659 = 8728018
419 + 8727599 = 8728018
449 + 8727569 = 8728018

Showing the first eight; more decompositions exist.
