Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647904, here are decompositions:

7 + 8647897 = 8647904
103 + 8647801 = 8647904
151 + 8647753 = 8647904
193 + 8647711 = 8647904
337 + 8647567 = 8647904
367 + 8647537 = 8647904
373 + 8647531 = 8647904
457 + 8647447 = 8647904

Showing the first eight; more decompositions exist.
