Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636650, here are decompositions:

3 + 8636647 = 8636650
17 + 8636633 = 8636650
23 + 8636627 = 8636650
47 + 8636603 = 8636650
59 + 8636591 = 8636650
101 + 8636549 = 8636650
107 + 8636543 = 8636650
137 + 8636513 = 8636650

Showing the first eight; more decompositions exist.
