Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739724, here are decompositions:

3 + 8739721 = 8739724
11 + 8739713 = 8739724
53 + 8739671 = 8739724
101 + 8739623 = 8739724
107 + 8739617 = 8739724
233 + 8739491 = 8739724
293 + 8739431 = 8739724
443 + 8739281 = 8739724

Showing the first eight; more decompositions exist.
