Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651940, here are decompositions:

23 + 8651917 = 8651940
47 + 8651893 = 8651940
71 + 8651869 = 8651940
83 + 8651857 = 8651940
137 + 8651803 = 8651940
149 + 8651791 = 8651940
223 + 8651717 = 8651940
229 + 8651711 = 8651940

Showing the first eight; more decompositions exist.
