Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651964, here are decompositions:

5 + 8651959 = 8651964
11 + 8651953 = 8651964
23 + 8651941 = 8651964
47 + 8651917 = 8651964
71 + 8651893 = 8651964
73 + 8651891 = 8651964
107 + 8651857 = 8651964
173 + 8651791 = 8651964

Showing the first eight; more decompositions exist.
