Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740724, here are decompositions:

43 + 8740681 = 8740724
67 + 8740657 = 8740724
163 + 8740561 = 8740724
193 + 8740531 = 8740724
271 + 8740453 = 8740724
277 + 8740447 = 8740724
313 + 8740411 = 8740724
331 + 8740393 = 8740724

Showing the first eight; more decompositions exist.
