Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687794, here are decompositions:

23 + 8687771 = 8687794
107 + 8687687 = 8687794
191 + 8687603 = 8687794
281 + 8687513 = 8687794
317 + 8687477 = 8687794
431 + 8687363 = 8687794
491 + 8687303 = 8687794
503 + 8687291 = 8687794

Showing the first eight; more decompositions exist.
