Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645654, here are decompositions:

7 + 8645647 = 8645654
37 + 8645617 = 8645654
67 + 8645587 = 8645654
163 + 8645491 = 8645654
211 + 8645443 = 8645654
223 + 8645431 = 8645654
313 + 8645341 = 8645654
373 + 8645281 = 8645654

Showing the first eight; more decompositions exist.
