Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640122, here are decompositions:

13 + 8640109 = 8640122
109 + 8640013 = 8640122
199 + 8639923 = 8640122
223 + 8639899 = 8640122
313 + 8639809 = 8640122
349 + 8639773 = 8640122
373 + 8639749 = 8640122
409 + 8639713 = 8640122

Showing the first eight; more decompositions exist.
