Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651396, here are decompositions:

7 + 8651389 = 8651396
37 + 8651359 = 8651396
43 + 8651353 = 8651396
67 + 8651329 = 8651396
73 + 8651323 = 8651396
157 + 8651239 = 8651396
163 + 8651233 = 8651396
277 + 8651119 = 8651396

Showing the first eight; more decompositions exist.
