Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656474, here are decompositions:

5 + 8656469 = 8656474
11 + 8656463 = 8656474
41 + 8656433 = 8656474
107 + 8656367 = 8656474
191 + 8656283 = 8656474
311 + 8656163 = 8656474
383 + 8656091 = 8656474
443 + 8656031 = 8656474

Showing the first eight; more decompositions exist.
