Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719788, here are decompositions:

17 + 8719771 = 8719788
41 + 8719747 = 8719788
89 + 8719699 = 8719788
107 + 8719681 = 8719788
127 + 8719661 = 8719788
197 + 8719591 = 8719788
211 + 8719577 = 8719788
239 + 8719549 = 8719788

Showing the first eight; more decompositions exist.
