Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640146, here are decompositions:

13 + 8640133 = 8640146
37 + 8640109 = 8640146
223 + 8639923 = 8640146
283 + 8639863 = 8640146
337 + 8639809 = 8640146
349 + 8639797 = 8640146
367 + 8639779 = 8640146
373 + 8639773 = 8640146

Showing the first eight; more decompositions exist.
