Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719724, here are decompositions:

43 + 8719681 = 8719724
61 + 8719663 = 8719724
151 + 8719573 = 8719724
157 + 8719567 = 8719724
241 + 8719483 = 8719724
283 + 8719441 = 8719724
397 + 8719327 = 8719724
421 + 8719303 = 8719724

Showing the first eight; more decompositions exist.
