Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651726, here are decompositions:

3 + 8651723 = 8651726
37 + 8651689 = 8651726
43 + 8651683 = 8651726
79 + 8651647 = 8651726
283 + 8651443 = 8651726
337 + 8651389 = 8651726
367 + 8651359 = 8651726
373 + 8651353 = 8651726

Showing the first eight; more decompositions exist.
