Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623724, here are decompositions:

3 + 8623721 = 8623724
7 + 8623717 = 8623724
37 + 8623687 = 8623724
73 + 8623651 = 8623724
103 + 8623621 = 8623724
331 + 8623393 = 8623724
367 + 8623357 = 8623724
433 + 8623291 = 8623724

Showing the first eight; more decompositions exist.
