Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621654, here are decompositions:

31 + 8621623 = 8621654
37 + 8621617 = 8621654
73 + 8621581 = 8621654
103 + 8621551 = 8621654
163 + 8621491 = 8621654
211 + 8621443 = 8621654
241 + 8621413 = 8621654
277 + 8621377 = 8621654

Showing the first eight; more decompositions exist.
