Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642564, here are decompositions:

31 + 8642533 = 8642564
97 + 8642467 = 8642564
181 + 8642383 = 8642564
283 + 8642281 = 8642564
367 + 8642197 = 8642564
457 + 8642107 = 8642564
487 + 8642077 = 8642564
577 + 8641987 = 8642564

Showing the first eight; more decompositions exist.
