Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723674, here are decompositions:

191 + 8723483 = 8723674
233 + 8723441 = 8723674
251 + 8723423 = 8723674
353 + 8723321 = 8723674
431 + 8723243 = 8723674
461 + 8723213 = 8723674
593 + 8723081 = 8723674
683 + 8722991 = 8723674

Showing the first eight; more decompositions exist.
