Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640674, here are decompositions:

73 + 8640601 = 8640674
127 + 8640547 = 8640674
181 + 8640493 = 8640674
193 + 8640481 = 8640674
223 + 8640451 = 8640674
283 + 8640391 = 8640674
337 + 8640337 = 8640674
433 + 8640241 = 8640674

Showing the first eight; more decompositions exist.
