Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636644, here are decompositions:

11 + 8636633 = 8636644
17 + 8636627 = 8636644
41 + 8636603 = 8636644
53 + 8636591 = 8636644
101 + 8636543 = 8636644
131 + 8636513 = 8636644
257 + 8636387 = 8636644
383 + 8636261 = 8636644

Showing the first eight; more decompositions exist.
