Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654664, here are decompositions:

23 + 8654641 = 8654664
43 + 8654621 = 8654664
47 + 8654617 = 8654664
101 + 8654563 = 8654664
181 + 8654483 = 8654664
197 + 8654467 = 8654664
211 + 8654453 = 8654664
233 + 8654431 = 8654664

Showing the first eight; more decompositions exist.
