Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613664, here are decompositions:

41 + 8613623 = 8613664
47 + 8613617 = 8613664
317 + 8613347 = 8613664
383 + 8613281 = 8613664
443 + 8613221 = 8613664
503 + 8613161 = 8613664
557 + 8613107 = 8613664
617 + 8613047 = 8613664

Showing the first eight; more decompositions exist.
