Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709644, here are decompositions:

271 + 8709373 = 8709644
283 + 8709361 = 8709644
331 + 8709313 = 8709644
373 + 8709271 = 8709644
457 + 8709187 = 8709644
523 + 8709121 = 8709644
577 + 8709067 = 8709644
673 + 8708971 = 8709644

Showing the first eight; more decompositions exist.
