Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746728, here are decompositions:

5 + 8746723 = 8746728
19 + 8746709 = 8746728
31 + 8746697 = 8746728
269 + 8746459 = 8746728
281 + 8746447 = 8746728
337 + 8746391 = 8746728
349 + 8746379 = 8746728
359 + 8746369 = 8746728

Showing the first eight; more decompositions exist.
