Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651724, here are decompositions:

7 + 8651717 = 8651724
13 + 8651711 = 8651724
31 + 8651693 = 8651724
41 + 8651683 = 8651724
61 + 8651663 = 8651724
97 + 8651627 = 8651724
181 + 8651543 = 8651724
223 + 8651501 = 8651724

Showing the first eight; more decompositions exist.
