Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640346, here are decompositions:

17 + 8640329 = 8640346
59 + 8640287 = 8640346
83 + 8640263 = 8640346
149 + 8640197 = 8640346
359 + 8639987 = 8640346
443 + 8639903 = 8640346
509 + 8639837 = 8640346
593 + 8639753 = 8640346

Showing the first eight; more decompositions exist.
