Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720674, here are decompositions:

3 + 8720671 = 8720674
47 + 8720627 = 8720674
191 + 8720483 = 8720674
197 + 8720477 = 8720674
227 + 8720447 = 8720674
257 + 8720417 = 8720674
353 + 8720321 = 8720674
503 + 8720171 = 8720674

Showing the first eight; more decompositions exist.
