Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640614, here are decompositions:

13 + 8640601 = 8640614
61 + 8640553 = 8640614
67 + 8640547 = 8640614
163 + 8640451 = 8640614
223 + 8640391 = 8640614
277 + 8640337 = 8640614
373 + 8640241 = 8640614
601 + 8640013 = 8640614

Showing the first eight; more decompositions exist.
