Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606642, here are decompositions:

43 + 8606599 = 8606642
151 + 8606491 = 8606642
199 + 8606443 = 8606642
211 + 8606431 = 8606642
229 + 8606413 = 8606642
241 + 8606401 = 8606642
313 + 8606329 = 8606642
349 + 8606293 = 8606642

Showing the first eight; more decompositions exist.
