Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671788, here are decompositions:

19 + 8671769 = 8671788
67 + 8671721 = 8671788
79 + 8671709 = 8671788
149 + 8671639 = 8671788
157 + 8671631 = 8671788
199 + 8671589 = 8671788
239 + 8671549 = 8671788
269 + 8671519 = 8671788

Showing the first eight; more decompositions exist.
