Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611664, here are decompositions:

31 + 8611633 = 8611664
67 + 8611597 = 8611664
163 + 8611501 = 8611664
223 + 8611441 = 8611664
241 + 8611423 = 8611664
283 + 8611381 = 8611664
307 + 8611357 = 8611664
367 + 8611297 = 8611664

Showing the first eight; more decompositions exist.
