Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711440, here are decompositions:

41 + 8711399 = 8711440
53 + 8711387 = 8711440
83 + 8711357 = 8711440
107 + 8711333 = 8711440
173 + 8711267 = 8711440
251 + 8711189 = 8711440
281 + 8711159 = 8711440
359 + 8711081 = 8711440

Showing the first eight; more decompositions exist.
