Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671744, here are decompositions:

5 + 8671739 = 8671744
23 + 8671721 = 8671744
47 + 8671697 = 8671744
113 + 8671631 = 8671744
227 + 8671517 = 8671744
233 + 8671511 = 8671744
281 + 8671463 = 8671744
317 + 8671427 = 8671744

Showing the first eight; more decompositions exist.
