Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649854, here are decompositions:

7 + 8649847 = 8649854
61 + 8649793 = 8649854
97 + 8649757 = 8649854
151 + 8649703 = 8649854
163 + 8649691 = 8649854
193 + 8649661 = 8649854
337 + 8649517 = 8649854
463 + 8649391 = 8649854

Showing the first eight; more decompositions exist.
