Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718644, here are decompositions:

43 + 8718601 = 8718644
73 + 8718571 = 8718644
157 + 8718487 = 8718644
331 + 8718313 = 8718644
367 + 8718277 = 8718644
373 + 8718271 = 8718644
397 + 8718247 = 8718644
541 + 8718103 = 8718644

Showing the first eight; more decompositions exist.
