Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636646, here are decompositions:

13 + 8636633 = 8636646
19 + 8636627 = 8636646
43 + 8636603 = 8636646
47 + 8636599 = 8636646
59 + 8636587 = 8636646
97 + 8636549 = 8636646
103 + 8636543 = 8636646
107 + 8636539 = 8636646

Showing the first eight; more decompositions exist.
