Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636684, here are decompositions:

13 + 8636671 = 8636684
37 + 8636647 = 8636684
97 + 8636587 = 8636684
103 + 8636581 = 8636684
151 + 8636533 = 8636684
163 + 8636521 = 8636684
193 + 8636491 = 8636684
211 + 8636473 = 8636684

Showing the first eight; more decompositions exist.
