Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642654, here are decompositions:

3 + 8642651 = 8642654
73 + 8642581 = 8642654
271 + 8642383 = 8642654
373 + 8642281 = 8642654
457 + 8642197 = 8642654
547 + 8642107 = 8642654
577 + 8642077 = 8642654
907 + 8641747 = 8642654

Showing the first eight; more decompositions exist.
