Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651340, here are decompositions:

11 + 8651329 = 8651340
17 + 8651323 = 8651340
29 + 8651311 = 8651340
43 + 8651297 = 8651340
59 + 8651281 = 8651340
73 + 8651267 = 8651340
79 + 8651261 = 8651340
101 + 8651239 = 8651340

Showing the first eight; more decompositions exist.
