Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636690, here are decompositions:

19 + 8636671 = 8636690
43 + 8636647 = 8636690
103 + 8636587 = 8636690
109 + 8636581 = 8636690
151 + 8636539 = 8636690
157 + 8636533 = 8636690
199 + 8636491 = 8636690
241 + 8636449 = 8636690

Showing the first eight; more decompositions exist.
