Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651644, here are decompositions:

5 + 8651639 = 8651644
17 + 8651627 = 8651644
41 + 8651603 = 8651644
101 + 8651543 = 8651644
107 + 8651537 = 8651644
137 + 8651507 = 8651644
347 + 8651297 = 8651644
383 + 8651261 = 8651644

Showing the first eight; more decompositions exist.
