Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718724, here are decompositions:

233 + 8718491 = 8718724
263 + 8718461 = 8718724
293 + 8718431 = 8718724
317 + 8718407 = 8718724
347 + 8718377 = 8718724
503 + 8718221 = 8718724
743 + 8717981 = 8718724
761 + 8717963 = 8718724

Showing the first eight; more decompositions exist.
