Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649662, here are decompositions:

193 + 8649469 = 8649662
199 + 8649463 = 8649662
211 + 8649451 = 8649662
271 + 8649391 = 8649662
313 + 8649349 = 8649662
331 + 8649331 = 8649662
379 + 8649283 = 8649662
409 + 8649253 = 8649662

Showing the first eight; more decompositions exist.
