Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687746, here are decompositions:

17 + 8687729 = 8687746
47 + 8687699 = 8687746
59 + 8687687 = 8687746
233 + 8687513 = 8687746
269 + 8687477 = 8687746
293 + 8687453 = 8687746
317 + 8687429 = 8687746
359 + 8687387 = 8687746

Showing the first eight; more decompositions exist.
