Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644600, here are decompositions:

47 + 8644553 = 8644600
71 + 8644529 = 8644600
89 + 8644511 = 8644600
101 + 8644499 = 8644600
149 + 8644451 = 8644600
269 + 8644331 = 8644600
347 + 8644253 = 8644600
443 + 8644157 = 8644600

Showing the first eight; more decompositions exist.
