Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697644, here are decompositions:

3 + 8697641 = 8697644
31 + 8697613 = 8697644
37 + 8697607 = 8697644
211 + 8697433 = 8697644
331 + 8697313 = 8697644
367 + 8697277 = 8697644
541 + 8697103 = 8697644
547 + 8697097 = 8697644

Showing the first eight; more decompositions exist.
