Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687944, here are decompositions:

53 + 8687891 = 8687944
71 + 8687873 = 8687944
173 + 8687771 = 8687944
257 + 8687687 = 8687944
431 + 8687513 = 8687944
467 + 8687477 = 8687944
491 + 8687453 = 8687944
521 + 8687423 = 8687944

Showing the first eight; more decompositions exist.
