Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684644, here are decompositions:

47 + 8684597 = 8684644
71 + 8684573 = 8684644
107 + 8684537 = 8684644
131 + 8684513 = 8684644
173 + 8684471 = 8684644
233 + 8684411 = 8684644
383 + 8684261 = 8684644
401 + 8684243 = 8684644

Showing the first eight; more decompositions exist.
