Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640106, here are decompositions:

47 + 8640059 = 8640106
89 + 8640017 = 8640106
197 + 8639909 = 8640106
257 + 8639849 = 8640106
269 + 8639837 = 8640106
353 + 8639753 = 8640106
359 + 8639747 = 8640106
443 + 8639663 = 8640106

Showing the first eight; more decompositions exist.
