Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613666, here are decompositions:

43 + 8613623 = 8613666
107 + 8613559 = 8613666
137 + 8613529 = 8613666
227 + 8613439 = 8613666
239 + 8613427 = 8613666
317 + 8613349 = 8613666
337 + 8613329 = 8613666
367 + 8613299 = 8613666

Showing the first eight; more decompositions exist.
