Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728606, here are decompositions:

149 + 8728457 = 8728606
179 + 8728427 = 8728606
233 + 8728373 = 8728606
317 + 8728289 = 8728606
569 + 8728037 = 8728606
617 + 8727989 = 8728606
797 + 8727809 = 8728606
827 + 8727779 = 8728606

Showing the first eight; more decompositions exist.
