Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616644, here are decompositions:

97 + 8616547 = 8616644
103 + 8616541 = 8616644
151 + 8616493 = 8616644
271 + 8616373 = 8616644
307 + 8616337 = 8616644
373 + 8616271 = 8616644
397 + 8616247 = 8616644
457 + 8616187 = 8616644

Showing the first eight; more decompositions exist.
