Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640466, here are decompositions:

47 + 8640419 = 8640466
59 + 8640407 = 8640466
137 + 8640329 = 8640466
179 + 8640287 = 8640466
269 + 8640197 = 8640466
449 + 8640017 = 8640466
479 + 8639987 = 8640466
557 + 8639909 = 8640466

Showing the first eight; more decompositions exist.
